Heikki Krogerus ab37fa851c usb: typec: Add type sysfs attribute file for partners
USB Power Delivery Specification defines a set of product
types for partners and cables. The product type can be read
from the ID Header VDO which is the first object in the
response to the Discover Identity command. This attribute
will display the product type of the partner. The cables
already have the attribute.

This sysfs attribute file is only created for the partners
and cables if the product type is really known in the
driver. Some interfaces do not give access to the Discover
Identity response from the partner or cable, but they may
still supply the product type separately in some cases.

When the product type of the partner or cable is detected,
uevent is also raised with PRODUCT_TYPE set to show the
actual product type (for example PRODUCT_TYPE=host).

Prashant Malani 2e70c495ca usb: typec: Expose Product Type VDOs via sysfs
A PD-capable device can return up to 3 Product Type VDOs as part of its
DiscoverIdentity Response (USB PD Spec, Rev 3.0, Version 2.0, Section
6.4.4.3.1). Add sysfs attributes to expose these to userspace.

Sai Praneeth Prakhya 63a816749d iommu: Document usage of "/sys/kernel/iommu_groups/<grp_id>/type" file
The default domain type of an iommu group can be changed by writing to
"/sys/kernel/iommu_groups/<grp_id>/type" file. Hence, document it's usage
and more importantly spell out its limitations.

Add a field to the typec_plug struct to record the number of available
altmodes as well as the corresponding sysfs attribute to expose this to
userspace.

This allows userspace to determine whether there are any
remaining alternate modes left to be registered by the kernel driver. It
can begin executing any policy state machine after all available
alternate modes have been registered with the connector class framework.

This value is set to "-1" initially, signifying that a valid number of
alternate modes haven't been set for the plug. The sysfs file remains
hidden as long as the attribute value is -1.

We re-use the partner attribute for number_of_alternate_modes since the
usage and name is similar, and update the corresponding *_show() command
to support both partner and plugs.

Daniel Borkmann says:

====================
pull-request: bpf-next 2020-11-14

1) Add BTF generation for kernel modules and extend BTF infra in kernel
   e.g. support for split BTF loading and validation, from Andrii Nakryiko.

2) Support for pointers beyond pkt_end to recognize LLVM generated patterns
   on inlined branch conditions, from Alexei Starovoitov.

3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh.

4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage
   infra, from Martin KaFai Lau.

5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the
   XDP_REDIRECT path, from Lorenzo Bianconi.

6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI
   context, from Song Liu.

7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build
   for different target archs on same source tree, from Jean-Philippe Brucker.

8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet.

9) Move functionality from test_tcpbpf_user into the test_progs framework so it
   can run in BPF CI, from Alexander Duyck.

10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner.

Note that for the fix from Song we have seen a sparse report on context
imbalance which requires changes in sparse itself for proper annotation
detection where this is currently being discussed on linux-sparse among
developers [0]. Once we have more clarification/guidance after their fix,
Song will follow-up.

tools to inspect module BTF contents and dump their types with existing tools:

Add support for the Intel Platform Monitoring Technology crashlog
interface. This interface provides a few sysfs values to allow for
controlling the crashlog telemetry interface as well as a character
driver to allow for mapping the crashlog memory region so that it can be
accessed after a crashlog has been recorded.

This driver is meant to only support the server version of the crashlog
which is identified as crash_type 1 with a version of zero. Currently no
other types are supported.

Alexander Duyck e2729113ce platform/x86: Intel PMT class driver
Intel Platform Monitoring Technology is meant to provide a common way to
access telemetry and system metrics.

Register mappings are not provided by the driver. Instead, a GUID is read
from a header for each endpoint. The GUID identifies the device and is to
be used with an XML, provided by the vendor, to discover the available set
of metrics and their register mapping.  This allows firmware updates to
modify the register space without needing to update the driver every time
with new mappings. Firmware writes a new GUID in this case to specify the
new mapping.  Software tools with access to the associated XML file can
then interpret the changes.

The module manages access to all Intel PMT endpoints on a system,
independent of the device exporting them. It creates an intel_pmt class
to manage the devices. For each telemetry endpoint, sysfs files provide
GUID and size information as well as a pointer to the parent device the
telemetry came from. Software may discover the association between
endpoints and devices by iterating through the list in sysfs, or by looking
for the existence of the class folder under the device of interest.  A
binary sysfs attribute of the same name allows software to then read or map
the telemetry space for direct access.

backlight class. This causes warnings:

	Warning: /sys/class/backlight/<backlight>/ambient_light_level is defined 2 times:  /sys/class/backlight/<backlight>/ambient_light_level:8  /sys/class/backlight/<backlight>/ambient_light_level:30

As ABI definitions shouldn't be duplicated.

Unfortunately, the ABI is dependent on the specific device
features. As such, ambient_light_level range is somewhat
different among the supported devices.

The ambient_light_zone is even worse: the meanings of each
preset are different, and there's no ABI to retrieve
the supported types nor their meanins. Unfortunately,
it is too late to fix it without causing regressions,
as this has been used since Kernel v2.6.35.

Rewrite those ABI documentation using the current documentation
as a reference, and double-checking at the datasheets:

	https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8870.pdf
	https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8860.pdf

Yet, both USB and Battery share a common set of charging-related
properties.

Unify the entries for such properties in order to avoid
duplication, while preserving the battery and USB-specific
data properly documented.

Chanwoo Choi 5f1a9066fc PM / devfreq: Add governor attribute flag for specifc sysfs nodes
DEVFREQ supports the default governors like performance, simple_ondemand and
also allows the devfreq driver to add their own governor like tegra30-devfreq.c
according to their requirement. In result, some sysfs attributes are useful
or not useful. Prior to that the user can access all sysfs attributes
regardless of the available attributes.

So, clarify the access permission of sysfs attributes according to governor.
When adding the devfreq governor, can specify the available attribute
information by using DEVFREQ_GOV_ATTR_* constant variable. The user can
read or write the sysfs attributes in accordance to the specified attributes.

When adding the governor, can add the following attributes
according to the governor feature.

[Definition for speific sysfs attributes]
- DEVFREQ_GOV_ATTR_POLLING_INTERVAL to update polling interval for timer.
  : /sys/class/devfreq/[devfreq dev name]/polling_interval
- DEVFREQ_GOV_ATTR_TIMER to change the type of timer on either deferrable
  or dealyed timer.
  : /sys/class/devfreq/[devfreq dev name]/timer

And all devfreq governors have to support the following common attributes.
The common attributes are added to devfreq class by default.
- governor
- available_governors
- available_frequencies
- cur_freq
- target_freq
- min_freq
- max_freq
- trans_stat

SeongJae Park 74a852479c xen-blkfront: add a parameter for disabling of persistent grants
Persistent grants feature provides high scalability.  On some small
systems, however, it could incur data copy overheads[1] and thus it is
required to be disabled.  It can be disabled from blkback side using a
module parameter, 'feature_persistent'.  But, it is impossible from
blkfront side.  For the reason, this commit adds a blkfront module
parameter for disabling of the feature.

SeongJae Park aac8a70db2 xen-blkback: add a parameter for disabling of persistent grants
Persistent grants feature provides high scalability.  On some small
systems, however, it could incur data copy overheads[1] and thus it is
required to be disabled.  But, there is no option to disable it.  For
the reason, this commit adds a module parameter for disabling of the
feature.

Linus Torvalds 7a3dadedc8 f2fs-for-5.10-rc1
In this round, we've added new features such as zone capacity for ZNS and
 a new GC policy, ATGC, along with in-memory segment management. In addition,
 we could improve the decompression speed significantly by changing virtual
 mapping method. Even though we've fixed lots of small bugs in compression
 support, I feel that it becomes more stable so that I could give it a try in
 production.
 
 Enhancement:
  - suport zone capacity in NVMe Zoned Namespace devices
  - introduce in-memory current segment management
  - add standart casefolding support
  - support age threshold based garbage collection
  - improve decompression speed by changing virtual mapping method
 
 Bug fix:
  - fix condition checks in some ioctl() such as compression, move_range, etc
  - fix 32/64bits support in data structures
  - fix memory allocation in zstd decompress
  - add some boundary checks to avoid kernel panic on corrupted image
  - fix disallowing compression for non-empty file
  - fix slab leakage of compressed block writes
 
 In addition, it includes code refactoring for better readability and minor
 bug fixes for compression and zoned device support.

Linus Torvalds c48b75b727 sound updates for 5.10
The amount of changes is smaller at this round (what a surprise),
 but lots of activity is seen.  Most of changes are about ASoC
 driver development, especially Intel platforms.
 Here are some highlights:
 
 General:
 * Replace all tasklet usages with other alternatives
 * Cleanup of the ASoC error unwinding code
 * Fixes for trivial issues caught by static checker
 * Spell fixes allover the places
 
 ALSA Core:
 * Lockdep fix for control devices
 * Fix for potential OSS sequencer mutex stalls
 
 HD-audio and USB-audio:
 * SoundBlaster AE-7 support
 * Changes in quirk table for the rename handling
 * Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2.
 
 ASoC:
 * Lots of updates for Intel SOF and SoundWire enablement
 * Replacement of the DSP driver for some older x86 systems;
   the new code was written from scratch, better maintenance
   expected
 * Helpers for parsing auxiluary devices from the device tree
 * New support for AllWinner A64, Cirrus Logic CS4234, Mediatek
   MT6359 Microchip S/PDIF TX and RX controllers, Realtek RT1015P,
   and Texas Instruments J721E, TAS2110, TAS2564 and TAS2764

    the OS interface layer and make it possible to access GPE registers
    using logical addresses if they are memory-mapped (Rafael Wysocki).
 
  - Update the ACPICA code in the kernel to upstream revision 20200925
    including changes as follows:
    * Add predefined names from the SMBus sepcification (Bob Moore).
    * Update acpi_help UUID list (Bob Moore).
    * Return exceptions for string-to-integer conversions in iASL (Bob
      Moore).
    * Add a new "ALL <NameSeg>" debugger command (Bob Moore).
    * Add support for 64 bit risc-v compilation (Colin Ian King).
    * Do assorted cleanups (Bob Moore, Colin Ian King, Randy Dunlap).
 
  - Add new ACPI backlight whitelist entry for HP 635 Notebook (Alex
    Hung).
 
  - Move TPS68470 OpRegion driver to drivers/acpi/pmic/ and split out
    Kconfig and Makefile specific for ACPI PMIC (Andy Shevchenko).
 
  - Clean up the ACPI SoC driver for AMD SoCs (Hanjun Guo).
 
  - Add missing config_item_put() to fix refcount leak (Hanjun Guo).
 
  - Drop lefrover field from struct acpi_memory_device (Hanjun Guo).
 
  - Make the ACPI extlog driver check for RDMSR failures (Ben
    Hutchings).
 
  - Fix handling of lid state changes in the ACPI button driver when
    input device is closed (Dmitry Torokhov).
 
  - Fix several assorted build issues (Barnabás Pőcze, John Garry,
    Nathan Chancellor, Tian Tao).
 
  - Drop unused inline functions and reduce code duplication by using
    kobj_to_dev() in the NFIT parsing code (YueHaibing, Wang Qing).
 
  - Serialize tools/power/acpi Makefile (Thomas Renninger).

Merge tag 'selinux-pr-20201012' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:
 "A decent number of SELinux patches for v5.10, twenty two in total. The
  highlights are listed below, but all of the patches pass our test
  suite and merge cleanly.

   - A number of changes to how the SELinux policy is loaded and managed
     inside the kernel with the goal of improving the atomicity of a
     SELinux policy load operation.

     These changes account for the bulk of the diffstat as well as the
     patch count. A special thanks to everyone who contributed patches
     and fixes for this work.

   - Convert the SELinux policy read-write lock to RCU.

   - A tracepoint was added for audited SELinux access control events;
     this should help provide a more unified backtrace across kernel and
     userspace.

   - Allow the removal of security.selinux xattrs when a SELinux policy
     is not loaded.

   - Enable policy capabilities in SELinux policies created with the
     scripts/selinux/mdp tool.

   - Provide some "no sooner than" dates for the SELinux checkreqprot
     sysfs deprecation"

Kajol Jain 09b791d955 powerpc/hv-gpci: Add sysfs files inside hv-gpci device to show cpumask
Patch here adds a cpumask attr to hv_gpci pmu along with ABI documentation.

Primary use to expose the cpumask is for the perf tool which has the
capability to parse the driver sysfs folder and understand the
cpumask file. Having cpumask file will reduce the number of perf command
line parameters (will avoid "-C" option in the perf tool
command line). It can also notify the user which is
the current cpu used to retrieve the counter data.

Sebastian Reichel 05f94eb989 power: supply: document current direction
Currently the sign for CURRENT_NOW and CURRENT_AVG is a bit
of a mess. There are basically 3 different ways battery fuel
gauges report the current:

1. uses negative values for discharging and positive values
   for charging
2. uses positive values for discharging and negative values
   for discharging (opposit of 1)
3. only uses positive values

As a result userspace currently cannot use the sign at all in
a generic way. Let's solve the issue by documenting a canonical
way for reporting the data and ensure new drivers follow this
way. Then existing drivers can be fixed on a case-by-case basis.

The 'negative value = battery discharging' has been choosen,
since there are only very few drivers doing it the other way
around.

Ivan Zaentsev 021da53e65 w1: w1_therm: Add sysfs entries to control conversion time and driver features
The conversion time of common DS18B20 clones deviates from
datasheet specs. Allow adjustment and automatic measure of the
conversion time.

Add 'conv_time' sysfs attribute:
  *read*: Current conversion time in milliseconds.
  *write*:
     '0': Set default conversion time.
     '1': Measure and set the conversion time. Make a
          single temperature conversion, poll and measure
          an actual value. Measured value is increased
          by 20% for temperature drift. A new conversion
          time is returned by reading the same attribute.
     other positive value:
        Set the conversion time in milliseconds.

The setting is active until a resolution change. Then it is reset to
default conversion time for a new resolution.

Add 'features' sysfs attribute to control optional driver settings
per device. Bit masks to read/write (logical OR):
  1: Enable check for conversion success. If byte 6 of
     scratchpad memory is 0xC after conversion, and
     temperature reads 85.00 (powerup value) or 127.94
     (insufficient power) - return a conversion error.

  2: Enable poll for conversion completion. Generate read cycles
     after the conversion start and wait for 1's. In parasite
     power mode this feature is not available.

There are some clones of DS18B20 with fixed 12 bit resolution. Make the
driver verify the resolution by reading back the device after resolution
change.

Xu Yilun 876611c493 mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PAC
This patch implements the basic functions of the BMC chip for some Intel
FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the
Intel MAX 10 CPLD.

This BMC chip is connected to the FPGA by a SPI bus. To provide direct
register access from the FPGA, the "SPI slave to Avalon Master Bridge"
(spi-avmm) IP is integrated in the chip. It converts encoded streams of
bytes from the host to the internal register read/write on the Avalon
bus. So This driver uses the regmap-spi-avmm for register accessing.

Paul Moore 0d50f059c4 selinux: provide a "no sooner than" date for the checkreqprot removal
We marked /sys/fs/selinux/checkreqprot as deprecated in Linux v5.7,
but didn't provide any guidance as to the timeframe.  Considering
the state of checkreqprot, it seems like one year should be enough
time.

Pierre-Louis Bossart 0173f525b2 soundwire: sysfs: add slave status and device number before probe
The MIPI DisCo device properties that are read by the driver from
platform firmware, or hard-coded in the driver, should only be
provided as sysfs entries when a driver probes successfully.

However the device status and device number is updated even when there
is no driver present, and hence can be updated when a Slave device is
detected on the bus without being described in platform firmware and
without any driver registered/probed.

As suggested by GregKH, the attribute group for Slave status and
device number is is added by default upon device registration.

Credits to Vinod Koul for the status_show() function, shared in a
separate patch and used as is here. The status table was modified to
remove an unnecessary enum and status_show() is handled in a different
group attribute than what was suggested by Vinod.

Oded Gabbay 2f55342c5e habanalabs: replace armcp with the generic cpucp
ArmCP mandates that the device CPU is always an ARM processor, which might
be wrong in the future.

Most of this change is an internal renaming of variables, functions and
defines but there are two entries in sysfs which have armcp in their
names. Add identical cpucp entries but don't remove yet the armcp entries.
Those will be deprecated next year. Add the documentation about it in sysfs
documentation.

Srinivas Pandruvada 2ce6324ead ACPI: DPTF: Add PCH FIVR participant driver
This driver adds support for Dynamic Platform and Thermal Framework
(DPTF) PCH (Platform Controller Hub) FIVR (Fully Integrated Voltage
Regulator) participant support.

This participant is responsible for exposing platform telemetry and
control for:
	freq_mhz_high_clock
	freq_mhz_low_clock

These attributes are used to get and set PCH FIVR switching frequency
for thermal and radio frequency interference mitigation.

Refer to Documentation/ABI/testing/sysfs-platform-dptf for ABI details.

ACPI methods description used in this driver:
RFC0: This ACPI method to set PCH FIVR switching frequency when FIVR
clock is 19.2MHz or 24MHz. The ACPI method takes a DWORD value.
GFC0: This ACPI method to get PCH FIVR switching frequency when FIVR
clock is 19.2MHz or 24MHz.
RFC1: This ACPI method to set PCH FIVR switching frequency when FIVR
clock is 38.4MHz. The ACPI method takes a DWORD value.
GFC1: This ACPI method to get PCH FIVR switching frequency when FIVR

Crt Mori dde8ceec9e iio: temperature: mlx90632: Interface to change object ambient temperature
Since object temperature might be different than the sensor temperature
the infrared sensors should provide an interface to inject ambient
temperature. This was in past done via write to ambient temperature
interface (in_temp_ambient_raw), but I think most people did not know
about it. This solution introduces a new iio type of the CALIBAMBIENT
which is hopefully more descriptive and more explicit about the purpose
and capabilities of the sensors.

Chao Yu 093749e296 f2fs: support age threshold based garbage collection
There are several issues in current background GC algorithm:
- valid blocks is one of key factors during cost overhead calculation,
so if segment has less valid block, however even its age is young or
it locates hot segment, CB algorithm will still choose the segment as
victim, it's not appropriate.
- GCed data/node will go to existing logs, no matter in-there datas'
update frequency is the same or not, it may mix hot and cold data
again.
- GC alloctor mainly use LFS type segment, it will cost free segment
more quickly.

This patch introduces a new algorithm named age threshold based
garbage collection to solve above issues, there are three steps
mainly:

1. select a source victim:
- set an age threshold, and select candidates beased threshold:
e.g.
 0 means youngest, 100 means oldest, if we set age threshold to 80
 then select dirty segments which has age in range of [80, 100] as
 candiddates;
- set candidate_ratio threshold, and select candidates based the
ratio, so that we can shrink candidates to those oldest segments;
- select target segment with fewest valid blocks in order to
migrate blocks with minimum cost;

2. select a target victim:
- select candidates beased age threshold;
- set candidate_radius threshold, search candidates whose age is
around source victims, searching radius should less than the
radius threshold.
- select target segment with most valid blocks in order to avoid
migrating current target segment.

3. merge valid blocks from source victim into target victim with
SSR alloctor.

Test steps:
- create 160 dirty segments:
 * half of them have 128 valid blocks per segment
 * left of them have 384 valid blocks per segment
- run background GC

Benefit: GC count and block movement count both decrease obviously:

- Before:
  - Valid: 86
  - Dirty: 1
  - Prefree: 11
  - Free: 6001 (6001)

GC calls: 162 (BG: 220)
  - data segments : 160 (160)
  - node segments : 2 (2)
Try to move 41454 blocks (BG: 41454)
  - data blocks : 40960 (40960)
  - node blocks : 494 (494)

IPU: 0 blocks
SSR: 0 blocks in 0 segments
LFS: 41364 blocks in 81 segments

- After:

  - Valid: 87
  - Dirty: 0
  - Prefree: 4
  - Free: 6008 (6008)

GC calls: 75 (BG: 76)
  - data segments : 74 (74)
  - node segments : 1 (1)

Xu Yilun 9ba3a0aa09 fpga: dfl: create a dfl bus type to support DFL devices
A new bus type "dfl" is introduced for private features which are not
initialized by DFL feature drivers (dfl-fme & dfl-afu drivers). So these
private features could be handled by separate driver modules.

DFL feature drivers (dfl-fme, dfl-port) will create DFL devices on
enumeration. DFL drivers could be registered on this bus to match these
DFL devices. They are matched by dfl type & feature_id.

Joel Stanley 4a851d714e fsi: aspeed: Support CFAM reset GPIO
Systems have a line for restting the remote CFAM. This is not part of
the FSI master, but is associated with it, so it makes sense to include
it in the master driver.

This exposes a sysfs interface to reset the cfam, abstracting away the
direction and polarity of the GPIO, as well as the timing of the reset
pulse. Userspace will be blocked until the reset pulse is finished.

The reset is hard coded to be in the range of (900, 1000) us. It was
observed with a scope to regularly be just over 1ms.

If the device tree property is not preset the driver will silently
continue.

Linus Torvalds 086ba2ec16 f2fs-for-5.9-rc1
In this round, we've added two small interfaces, 1) GC_URGENT_LOW mode for
 performance, and 2) F2FS_IOC_SEC_TRIM_FILE ioctl for security. The new GC
 mode allows Android to run some lower priority GCs in background, while new
 ioctl discards user information without race condition when the account is
 removed. In addition, some patches were merged to address latency-related
 issues. We've fixed some compression-related bug fixes as well as edge race
 conditions.
 
 Enhancement:
  - add GC_URGENT_LOW mode in gc_urgent
  - introduce F2FS_IOC_SEC_TRIM_FILE ioctl
  - bypass racy readahead to improve read latencies
  - shrink node_write lock coverage to avoid long latency
 
 Bug fix:
  - fix missing compression flag control, i_size, and mount option
  - fix deadlock between quota writes and checkpoint
  - remove inode eviction path in synchronous path to avoid deadlock
  - fix to wait GCed compressed page writeback
  - fix a kernel panic in f2fs_is_compressed_page
  - check page dirty status before writeback
  - wait page writeback before update in node page write flow
  - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry
 
 We've added some minor sanity checks and refactored trivial code blocks for
 better readability and debugging information.

Linus Torvalds 25d8d4eeca powerpc updates for 5.9
- Add support for (optionally) using queued spinlocks & rwlocks.
 
  - Support for a new faster system call ABI using the scv instruction on Power9
    or later.
 
  - Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on
    Power10 and future processors, leaving us with no way to implement the
    functionality it requests. This risks breaking userspace, though we believe
    it is unused in practice.
 
  - A bug fix for, and then the removal of, our custom stack expansion checking.
    We now allow stack expansion up to the rlimit, like other architectures.
 
  - Remove the remnants of our (previously disabled) topology update code, which
    tried to react to NUMA layout changes on virtualised systems, but was prone
    to crashes and other problems.
 
  - Add PMU support for Power10 CPUs.
 
  - A change to our signal trampoline so that we don't unbalance the link stack
    (branch return predictor) in the signal delivery path.
 
  - Lots of other cleanups, refactorings, smaller features and so on as usual.

Sebastian Reichel d862a3068e Input: exc3000 - add support to query model and fw_version
Expose model and fw_version via sysfs. Also query the model
in probe to make sure, that the I2C communication with the
device works before successfully probing the driver.

This is a bit complicated, since EETI devices do not have
a sync interface. Sending the commands and directly reading
does not work. Sending the command and waiting for some time
is also not an option, since there might be touch events in
the mean time.

Last but not least we do not cache the results, since this
interface can be used to check the I2C communication is still
working as expected.

Linus Torvalds c0c419c045 Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1.
 
 Lots of churn here, but overall the size increase in lines added is
 small, while adding a load of new IIO drivers.
 
 Major things in here:
 	- lots and lots of IIO new drivers and frameworks added
 	- IIO driver fixes and updates
 	- lots of tiny coding style cleanups for staging drivers
 	- vc04_services major reworks and cleanups
 
 We had 3 set of drivers move out of staging in this round as well:
 	- wilc1000 wireless driver moved out of staging
 	- speakup moved out of staging
 	- most USB driver moved out of staging
 
 Full details are in the shortlog.
 
 All of these have been in linux-next with no reported issues.  The last
 few changes here were to resolve reported linux-next issues, and they
 seem to have resolved the problems.

  Major things in here:

   - lots and lots of IIO new drivers and frameworks added

   - IIO driver fixes and updates

   - lots of tiny coding style cleanups for staging drivers

   - vc04_services major reworks and cleanups

  We had 3 set of drivers move out of staging in this round as well:

   - wilc1000 wireless driver moved out of staging

   - speakup moved out of staging

   - most USB driver moved out of staging

  Full details are in the shortlog.

  All of these have been in linux-next with no reported issues. The last
  few changes here were to resolve reported linux-next issues, and they
  seem to have resolved the problems"

Linus Torvalds e4a7b2dc35 LEDs changes for 5.9-rc1.
Okay, so... this one is interesting. RGB LEDs are very common, and we
 need to have some kind of support for them. Multicolor is for
 arbitrary set of LEDs in one package, RGB is for LEDs that can produce
 full range of colors. We do not have real multicolor LED that is not
 RGB in the pipeline, so that one is disabled for now.
 
 You can expect this saga to continue with next pull requests.

Linus Torvalds dd27111e32 Driver core changes for 5.9-rc1
Here is the "big" set of changes to the driver core, and some drivers
 using the changes, for 5.9-rc1.
 
 "Biggest" thing in here is the device link exposure in sysfs, to help
 to tame the madness that is SoC device tree representations and driver
 interactions with it.
 
 Other stuff in here that is interesting is:
 	- device probe log helper so that drivers can report problems in
 	  a unified way easier.
 	- devres functions added
 	- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
 	  incorrect sysfs file permissions
 	- documentation cleanups
 	- ability for debugfs to be present in the kernel, yet not
 	  exposed to userspace.  Needed for systems that want it
 	  enabled, but do not trust users, so they can still use some
 	  kernel functions that were otherwise disabled.
 	- other minor fixes and cleanups
 
 The patches outside of drivers/base/ all have acks from the respective
 subsystem maintainers to go through this tree instead of theirs.
 
 All of these have been in linux-next with no reported issues.

Pull power management updates from Rafael Wysocki:
 "The most significant change here is the extension of the Energy Model
  to cover non-CPU devices (as well as CPUs) from Lukasz Luba.

  There is also some new hardware support (Ice Lake server idle states
  table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
  RAPL driver), some new functionality in the existing drivers (eg. a
  new switch to disable/enable CPU energy-efficiency optimizations in
  intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
  core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
  devfreq), including the elimination of W=1 build warnings from cpufreq
  done by Lee Jones.

  Specifics:

   - Make the Energy Model cover non-CPU devices (Lukasz Luba).

   - Add Ice Lake server idle states table to the intel_idle driver and
     eliminate a redundant static variable from it (Chen Yu, Rafael
     Wysocki).

Linus Torvalds 822ef14e9d ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
 to have the code merged through the soc tree as upstream, as the code
 tends to be used across multiple SoCs or has SoC specific drivers itself:
 
  - memory controllers:
      Krzysztof Kozlowski takes ownership of the drivers/memory
      subsystem and its drivers, starting out with a set of cleanup
      patches.
      A larger driver for the Tegra memory controller that was accidentally
      missed for v5.8 is now added.
 
  - reset controllers:
      Only minor updates to drivers/reset this time
 
  - firmware:
      The "turris mox" firmware driver gains support for signed firmware blobs
      The tegra firmware driver gets extended to export some debug information
      Various updates to i.MX firmware drivers, mostly cosmetic
 
  - ARM SCMI/SCPI:
      A new mechanism for platform notifications is added, among a number
      of minor changes.
 
  - optee:
      Probing of the TEE bus is rewritten to better support detection of
      devices that depend on the tee-supplicant user space.
      A new firmware based trusted platform module (fTPM) driver is added
      based on OP-TEE
 
  - SoC attributes:
      A new driver is added to provide a generic soc_device for identifying
      a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
      by probing SoC family specific registers.
      The series also contains some cleanups to the common soc_device code.
 
 There are also a number of updates to SoC specific drivers,
 the main ones are:
 
  - Mediatek cmdq driver gains a few in-kernel interfaces
 
  - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
    support for additional SoC variants
 
  - The Qualcomm GENI core code gains interconnect path voting and
    performance level support, and integrating this into a number of
    device drivers.
 
  - A new driver for Samsung Exynos5800 voltage coupler for
 
  - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
    specific device drivers
 
  - Updates to the TI K3 Ring Accelerator driver

During NVDIMM probe time in papr_scm_nvdimm_init() a special variant
of H_SCM_PERFORMANCE_STATS hcall is issued to check if collection of
performance statistics is supported or not. If successful then a PHYP
returns a maximum possible buffer length needed to read all
performance stats. This returned value is stored in a per-nvdimm
attribute 'stat_buffer_len'.

The layout of request buffer for reading NVDIMM performance stats from
PHYP is defined in 'struct papr_scm_perf_stats' and 'struct
papr_scm_perf_stat'. These structs are used in newly introduced
drc_pmem_query_stats() that issues the H_SCM_PERFORMANCE_STATS hcall.

The sysfs access function perf_stats_show() uses value
'stat_buffer_len' to allocate a buffer large enough to hold all
possible NVDIMM performance stats and passes it to
drc_pmem_query_stats() to populate. Finally statistics reported in the
buffer are formatted into the sysfs access function output buffer.

Crag Wang 46cbd0b057 power: supply: wilco_ec: Add long life charging mode
This is a long life mode set in the factory for extended warranty
battery, the power charging rate is customized so that battery at
work last longer.

Presently switching to a different battery charging mode is through
EC PID 0x0710 to configure the battery firmware, this operation will
be blocked by EC with failure code 0x01 when PLL mode is already
in use.

Chanwoo Choi 4dc3bab868 PM / devfreq: Add support delayed timer for polling mode
Until now, the devfreq driver using polling mode like simple_ondemand
governor have used only deferrable timer for reducing the redundant
power consumption. It reduces the CPU wake-up from idle due to polling mode
which check the status of Non-CPU device.

But, it has a problem for Non-CPU device like DMC device with DMA operation.
Some Non-CPU device need to do monitor continuously regardless of CPU state
in order to decide the proper next status of Non-CPU device.

So, add support the delayed timer for polling mode to support
the repetitive monitoring. The devfreq driver and user can select
the kind of timer on either deferrable and delayed timer.

For example, change the timer type of DMC device
based on Exynos5422-based Odroid-XU3 as following:

- If want to use deferrable timer as following:
echo deferrable > /sys/class/devfreq/10c20000.memory-controller/timer

- If want to use delayed timer as following:
echo delayed > /sys/class/devfreq/10c20000.memory-controller/timer

Alexander Usyskin 2f79d3d1f7 mei: add device kind to sysfs
Some of the mei device heads are not generic and have
a specific purpose, we need to announce it to the user space
so it is possible to detect the correct device node via
matching attributes.

Generic heads are marked as 'mei' while special purpose heads
have their own names. Currently we are adding 'itouch' string
for Intel IPTS 1.0, 2.0 devices.

This is done via new sysfs attribute 'kind'.

Dan Williams a1facc1fff ACPI: NFIT: Add runtime firmware activate support
Plumb the platform specific backend for the generic libnvdimm firmware
activate interface. Register dimm level operations to arm/disarm
activation, and register bus level operations to report the dynamic
platform-quiesce time relative to the number of dimms armed for firmware
activation.

A new nfit-specific bus attribute "firmware_activate_noidle" is added to
allow the activation to switch between platform enforced, and OS
opportunistic device quiesce. In other words, let the hibernate cycle
handle in-flight device-dma rather than the platform attempting to
increase PCI-E timeouts and the like.

Dan Williams 48001ea50d PM, libnvdimm: Add runtime firmware activation support
Abstract platform specific mechanics for nvdimm firmware activation
behind a handful of generic ops. At the bus level ->activate_state()
indicates the unified state (idle, busy, armed) of all DIMMs on the bus,
and ->capability() indicates the system state expectations for activate.
At the DIMM level ->activate_state() indicates the per-DIMM state,
->activate_result() indicates the outcome of the last activation
attempt, and ->arm() attempts to transition the DIMM from 'idle' to
'armed'.

A new hibernate_quiet_exec() facility is added to support firmware
activation in an OS defined system quiesce state. It leverages the fact
that the hibernate-freeze state wants to assert that a memory
hibernation snapshot can be taken. This is in contrast to a platform
firmware defined quiesce state that may forcefully quiet the memory
controller independent of whether an individual device-driver properly
supports hibernate-freeze.

The libnvdimm sysfs interface is extended to support detection of a
firmware activate capability. The mechanism supports enumeration and
triggering of firmware activate, optionally in the
hibernate_quiet_exec() context.

Greg Kroah-Hartman f6b35db072 First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
 from Alexandru. Some of this has been in Analog's tree a long time, but other
 parts are motivated by closing down common mistakes in new drivers.
 
 Changes since first try at this pull request:
 * Add missed patch to actually remove iio_priv_to_dev and as a result
   also drop a few ingenic patches that need to be updated to take this
   into account.
 * Fix an ordering issue int he pollfunc attach in the core rework.
 
 New device support
 * qcom pmic7 adc
   - New driver using common qcom-vadc library. Some associated cleanups and
     refactors.
 * invensense icm42600
   - New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
     or spi.  These are all 6 axis IMUs with gyro and accelerometers.
     Driver supports buffered modes using the hardware fifo and interpolation
     for accurate timestamps.
 * sensirion scd30
   - New driver for this carbon dioxide sensor including i2c and serial
     interfaces + bindings.
 
 Features
 * ak8975
   - Add reset gpio support.
 * bma400
   - Support SPI.
 * bmc150
   - Document and add support for bmc156b and bmm150b, tidy up _magn endings.
 * bmi160
   - Regulator and mount matrix support.
 * mxc4005
   - Add ID for mxc6655
 * rockchip-saradc
   - Triggered buffer support.
 
 DT bindings
 * qcom spmi-vadc converted to yaml + pmic7 bindings
 * ak8975 tidy up and convert to yaml + add reset-gpio binding
 * ingenic-adc -convert to yaml.
 
 Core rework all carried through by Alexandru Ardelean.
 * Assign parent device in the core rather than every driver. A few devices
   need to provide specific non standard parents, so there is support for
   overriding.
 * Start to take parts of struct iio_dev opaque to the drivers.
   This will be a long term job, but should reduce the number of drivers
   we get that use parts that are currently only 'internal' by documentation.
 * Move attach and detach of pollfunc to the core.  Every triggered buffer
   using driver had to do the same thing, so lets do it in the core.  The
   hard part here was getting all the drivers into canonical form so there
   would be no functional changes in this final patch.  That's taken quite
   a lot of work over last couple of cycles!
 
 Cleanups and minor fixes.
 * docs
   - Improve IIO_CONCENTRATION channel type description in ABI docs.
   - Drop doubled word cases.
   - Http to Https conversion.
 * core
   - Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
     nasty casts.
 * ADCs
   - Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
     and CONFIG_OF protections.  These prevent use of ACPI PRP0001 with these
     drivers and get coppied into lots of new drivers.
 * ad5380
   - Constify iio_chan_spec_ext_info
 * ad5592r
   - Constify iio_chan_spec_ext_info
   - Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
 * ad8366
   - Make gpio optional as doesn't matter if its there or not.
 * adis16480
   - Use irq types instead of the flags.
 * atlas-ezo-sensor
   - Minimize scope of ret variable.
 * at91-adc

Merge tag 'iio-for-5.9a-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of new device support, cleanups and features for IIO in the 5.9 cycle

Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.

Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
  also drop a few ingenic patches that need to be updated to take this
  into account.
* Fix an ordering issue int he pollfunc attach in the core rework.

New device support
* qcom pmic7 adc
  - New driver using common qcom-vadc library. Some associated cleanups and
    refactors.
* invensense icm42600
  - New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
    or spi.  These are all 6 axis IMUs with gyro and accelerometers.
    Driver supports buffered modes using the hardware fifo and interpolation
    for accurate timestamps.
* sensirion scd30
  - New driver for this carbon dioxide sensor including i2c and serial
    interfaces + bindings.

Features
* ak8975
  - Add reset gpio support.
* bma400
  - Support SPI.
* bmc150
  - Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
  - Regulator and mount matrix support.
* mxc4005
  - Add ID for mxc6655
* rockchip-saradc
  - Triggered buffer support.

DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.

Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
  need to provide specific non standard parents, so there is support for
  overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
  This will be a long term job, but should reduce the number of drivers
  we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core.  Every triggered buffer
  using driver had to do the same thing, so lets do it in the core.  The
  hard part here was getting all the drivers into canonical form so there
  would be no functional changes in this final patch.  That's taken quite
  a lot of work over last couple of cycles!

Cleanups and minor fixes.
* docs
  - Improve IIO_CONCENTRATION channel type description in ABI docs.
  - Drop doubled word cases.
  - Http to Https conversion.
* core
  - Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
    nasty casts.
* ADCs
  - Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
    and CONFIG_OF protections.  These prevent use of ACPI PRP0001 with these
    drivers and get coppied into lots of new drivers.
* ad5380
  - Constify iio_chan_spec_ext_info
* ad5592r
  - Constify iio_chan_spec_ext_info
  - Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ad8366
  - Make gpio optional as doesn't matter if its there or not.
* adis16480
  - Use irq types instead of the flags.
* atlas-ezo-sensor
  - Minimize scope of ret variable.
* at91-adc
  - Add COMPILE_TEST dependency to driver to improve build coverage.
  - Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* at91-sama5d2
  - Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
  - Drop Ludovic as a co-maintaienr.
* cros_ec
  - Reapply the range after resume.
  - Add a read only frequency entry for legacy version.
  - Typo fixes
* hts221
  - Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* inv_mpu
  - Drop double check on ACPI companion device.
* iqs621

Kajol Jain 792f73f747 powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show cpumask
Patch here adds a cpumask attr to hv_24x7 pmu along with ABI documentation.

Primary use to expose the cpumask is for the perf tool which has the
capability to parse the driver sysfs folder and understand the
cpumask file. Having cpumask file will reduce the number of perf command
line parameters (will avoid "-C" option in the perf tool
command line). It can also notify the user which is
the current cpu used to retrieve the counter data.

command:# cat /sys/devices/hv_24x7/interface/cpumask

Niklas Cassel 659bf827ba block: add max_active_zones to blk-sysfs
Add a new max_active zones definition in the sysfs documentation.
This definition will be common for all devices utilizing the zoned block
device support in the kernel.

Export max_active_zones according to this new definition for NVMe Zoned
Namespace devices, ZAC ATA devices (which are treated as SCSI devices by
the kernel), and ZBC SCSI devices.

Add the new max_active_zones member to struct request_queue, rather
than as a queue limit, since this property cannot be split across stacking
drivers.

For SCSI devices, even though max active zones is not part of the ZBC/ZAC
spec, export max_active_zones as 0, signifying "no limit".

Bruno Meneguele bc885f1ab6 doc:kmsg: explicitly state the return value in case of SEEK_CUR
The commit 625d344978 ("Revert "kernel/printk: add kmsg SEEK_CUR
handling"") reverted a change done to the return value in case a SEEK_CUR
operation was performed for kmsg buffer based on the fact that different
userspace apps were handling the new return value (-ESPIPE) in different
ways, breaking them.

At the same time -ESPIPE was the wrong decision because kmsg /does support/
seek() but doesn't follow the "normal" behavior userspace is used to.
Because of that and also considering the time -EINVAL has been used, it was
decided to keep this way to avoid more userspace breakage.

This patch adds an official statement to the kmsg documentation pointing to
the current return value for SEEK_CUR, -EINVAL, thus userspace libraries
and apps can refer to it for a definitive guide on what to expect.

Saravana Kannan da6d647598 driver core: Add waiting_for_supplier sysfs file for devices
This would be useful to check if a device is not probing because it's
waiting for a supplier to be added and then linked to before it can
probe.

To reduce sysfs clutter, this file is added only if it can ever be 1.
So, if fw_devlink is disabled or set to permissive, this file is not
added. Also, this file is removed once the device probes as it's no
longer relevant.

SoC attributes update for v5.9

1. Addition of ARM SMCCC ARCH_SOC_ID support
2. Usage of the custom soc attribute groups already supported in the
   infrastucture instead of device_create_file which eliminates the need
   for any cleanup when soc is unregistered
3. Minor clean up switching to use standard DEVICE_ATTR_RO() instead of
   direct __ATTR

Sudeep Holla 821b67fa46 firmware: smccc: Add ARCH_SOC_ID support
SMCCC v1.2 adds a new optional function SMCCC_ARCH_SOC_ID to obtain a
SiP defined SoC identification value. Add support for the same.

Also using the SoC bus infrastructure, let us expose the platform
specific SoC atrributes under sysfs.

There are various ways in which it can be represented in shortened form
for efficiency and ease of parsing for userspace. The chosen form is
described in the ABI document.

Kranthi Kuntala dacb12877d thunderbolt: Add support for on-board retimers
USB4 spec specifies standard access to retimers (both on-board and
cable) through USB4 port sideband access. This makes it possible to
upgrade their firmware in the same way than we already do with the
routers.

This enumerates on-board retimers under each USB4 port when the link
comes up and adds them to the bus under the router the retimer belongs
to. Retimers are exposed in sysfs with name like <device>:<port>.<index>
where device is the router the retimer belongs to, port is the USB4 port
the retimer is connected to and index is the retimer index under that
port (starting from 1). This applies to the upstream USB4 port as well
so if there is on-board retimer between the port and the router it is
also added accordingly.

At this time we do not add cable retimers but there is no techincal
restriction to do so in the future if needed. It is not clear whether it
makes sense to upgrade their firmwares and at least Thunderbolt 3 cables
it has not been done outside of lab environments.

The sysfs interface is made to follow the router NVM upgrade to make it
easy to extend the existing userspace (fwupd) to handle these as well.

Jason A. Donenfeld 625d344978 Revert "kernel/printk: add kmsg SEEK_CUR handling"
This reverts commit 8ece3b3eb5.

This commit broke userspace. Bash uses ESPIPE to determine whether or
not the file should be read using "unbuffered I/O", which means reading
1 byte at a time instead of 128 bytes at a time. I used to use bash to
read through kmsg in a really quite nasty way:

    while read -t 0.1 -r line 2>/dev/null || [[ $? -ne 142 ]]; do
       echo "SARU $line"
    done < /dev/kmsg

This will show all lines that can fit into the 128 byte buffer, and skip
lines that don't. That's pretty awful, but at least it worked.

With this change, bash now tries to do 1-byte reads, which means it
skips all the lines, which is worse than before.

Now, I don't really care very much about this, and I'm already look for
a workaround. But I did just spend an hour trying to figure out why my
scripts were broken. Either way, it makes no difference to me personally
whether this is reverted, but it might be something to consider. If you
declare that "trying to read /dev/kmsg with bash is terminally stupid
anyway," I might be inclined to agree with you. But do note that bash
uses lseek(fd, 0, SEEK_CUR)==>ESPIPE to determine whether or not it's
reading from a pipe.

Vaibhav Jain b791abf320 powerpc/papr_scm: Fetch nvdimm health information from PHYP

H_SCM_HEALTH hcall as documented in Ref[1]. The hcall returns a pair
of 64-bit bitmap, bitwise-and of which is then stored in
'struct papr_scm_priv' and subsequently partially exposed to
user-space via newly introduced dimm specific attribute
'papr/flags'. Since the hcall is costly, the health information is
cached and only re-queried, 60s after the previous successful hcall.

The patch also adds a  documentation text describing flags reported by

Linus Torvalds 42612e7763 f2fs-for-5.8-rc1
In this round, we've added some knobs to enhance compression feature and harden
 testing environment. In addition, we've fixed several bugs reported from Android
 devices such as long discarding latency, device hanging during quota_sync, etc.
 
 Enhancement:
 - support lzo-rle algorithm
 - add two ioctls to release and reserve blocks for compression
 - support partial truncation/fiemap on compressed file
 - introduce sysfs entries to attach IO flags explicitly
 - add iostat trace point along with read io stat
 
 Bug fix:
 - fix long discard latency
 - flush quota data by f2fs_quota_sync correctly
 - fix to recover parent inode number for power-cut recovery
 - fix lz4/zstd output buffer budget
 - parse checkpoint mount option correctly
 - avoid inifinite loop to wait for flushing node/meta pages
 - manage discard space correctly
 
 And some refactoring and clean up patches were added.

Pull x86 srbds fixes from Thomas Gleixner:
 "The 9th episode of the dime novel "The performance killer" with the
  subtitle "Slow Randomizing Boosts Denial of Service".

  SRBDS is an MDS-like speculative side channel that can leak bits from
  the random number generator (RNG) across cores and threads. New
  microcode serializes the processor access during the execution of
  RDRAND and RDSEED. This ensures that the shared buffer is overwritten
  before it is released for reuse. This is equivalent to a full bus
  lock, which means that many threads running the RNG instructions in
  parallel have the same effect as the same amount of threads issuing a
  locked instruction targeting an address which requires locking of two
  cachelines at once.

  The mitigation support comes with the usual pile of unpleasant
  ingredients:

   - command line options

   - sysfs file

   - microcode checks

   - a list of vulnerable CPUs identified by model and stepping this
     time which requires stepping match support for the cpu match logic.

   - the inevitable slowdown of affected CPUs"

Pull powerpc updates from Michael Ellerman:

 - Support for userspace to send requests directly to the on-chip GZIP
   accelerator on Power9.

 - Rework of our lockless page table walking (__find_linux_pte()) to
   make it safe against parallel page table manipulations without
   relying on an IPI for serialisation.

 - A series of fixes & enhancements to make our machine check handling
   more robust.

 - Lots of plumbing to add support for "prefixed" (64-bit) instructions
   on Power10.

 - Support for using huge pages for the linear mapping on 8xx (32-bit).

 - Remove obsolete Xilinx PPC405/PPC440 support, and an associated sound
   driver.

 - Removal of some obsolete 40x platforms and associated cruft.

 - Initial support for booting on Power10.

 - Lots of other small features, cleanups & fixes.

Merge tag 'media/v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Media documentation is now split into admin-guide, driver-api and
   userspace-api books (a longstanding request from Jon);

 - The media Kconfig was reorganized, in order to make easier to select
   drivers and their dependencies;

 - The testing drivers now has a separate directory;

 - added a new driver for Rockchip Video Decoder IP;

 - The atomisp staging driver was resurrected. It is meant to work with
   4 generations of cameras on Atom-based laptops, tablets and cell
   phones. So, it seems worth investing time to cleanup this driver and
   making it in good shape.

 - Added some V4L2 core ancillary routines to help with h264 codecs;

 - Added an ov2740 image sensor driver;

 - The si2157 gained support for Analog TV, which, in turn, added
   support for some cx231xx and cx23885 boards to also support analog
   standards;

 - Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
   V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
   is located at the device;

 - VIDIOC_ENUM_FMT was extended to support MC-centric devices;

 - Lots of drivers improvements and cleanups.

    * Make the intel_pstate driver start in the passive mode by
      default on systems without HWP (Rafael Wysocki).
 
    * Add i.MX7ULP support to the imx-cpufreq-dt driver and add
      i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
 
    * Convert the qoriq cpufreq driver to a platform one, make the
      platform code create a suitable device object for it and add
      platform dependencies to it (Mian Yousaf Kaukab, Geert
      Uytterhoeven).
 
    * Fix wrong compatible binding in the qcom driver (Ansuel Smith).

  - Add ElkhartLake support to the Intel RAPL power capping driver
    and remove an unused local MSR definition from it (Jacob Pan,
    Sumeet Pawnikar).
 
  - Update devfreq core and drivers:
 
    * Replace strncpy() with strscpy() in the devfreq core and use
      lockdep asserts instead of manual checks for a locked mutex in
      it (Dmitry Osipenko, Krzysztof Kozlowski).
 
    * Add a generic imx bus scaling driver and make it register an
      interconnect device (Leonard Crestez, Gustavo A. R. Silva).

Linus Torvalds b23c4771ff A fair amount of stuff this time around, dominated by yet another massive
set from Mauro toward the completion of the RST conversion.  I *really*
 hope we are getting close to the end of this.  Meanwhile, those patches
 reach pretty far afield to update document references around the tree;
 there should be no actual code changes there.  There will be, alas, more of
 the usual trivial merge conflicts.
 
 Beyond that we have more translations, improvements to the sphinx
 scripting, a number of additions to the sysctl documentation, and lots of
 fixes.

 - Benjamin Herrenschmidt solved a problem with non-matched console
   aliases by first checking consoles defined on the command line. It is
   a more conservative approach than the previous attempts.

 - Benjamin also made sure that the console accessible via /dev/console
   always has CON_CONSDEV flag.

 - Andy Shevchenko added the %ptT modifier for printing struct time64_t.
   It extends the existing %ptR handling for struct rtc_time.

 - Bruno Meneguele fixed /dev/kmsg error value returned by unsupported
   SEEK_CUR.

 - Tetsuo Handa removed unused pr_cont_once().

... and a few small fixes.

Srinivas Pandruvada 7b52b200cf ACPI: DPTF: Add battery participant driver
This driver adds support for Dynamic Platform and Thermal Framework
battery participant device support.

These attributes are presented via sysfs interface under the platform
device for the battery participant:
$ls /sys/bus/platform/devices/INT3532:00/dptf_battery
	current_discharge_capbility_ma
	max_platform_power_mw
	no_load_voltage_mv
	high_freq_impedance_mohm
	max_steady_state_power_mw

Refer to the documentation at
Documentation/ABI/testing/sysfs-platform-dptf
for details.

Here the implementation reuses existing dptf-power.c as the motivation and
processing is same. It also shares one ACPI method. Here this change is
using participant type, "PTYP" method to identify and do different
processing. By using participant type, create/delete either "dptf_power"
or "dptf_battery" attribute group and send notifications.

The particpant type for for the battery participant is 0x0C.

ACPI methods description:

PMAX (Intel(R) Dynamic Tuning Platform Max Power Supplied by Battery):
This object evaluates to the maximum platform power that can be supported
by the battery in milli watts.

PBSS (Intel(R) Dynamic Tuning Power Battery Steady State):
This object returns the max sustained power for battery in milli watts.

RBHF (Intel(R) Dynamic Tuning High Frequency Impedance):
This object returns high frequency impedance value that can be obtained
from battery fuel gauge.

VBNL (Intel(R) Dynamic Tuning No-Load Voltage)
This object returns battery instantaneous no-load voltage that can be
obtained from battery fuel gauge in milli volts

CMPP (Intel(R) Dynamic Tuning Current Discharge Capability)
This object returns battery discharge current capability obtained from
battery fuel gauge milli amps.

Notifications:

0x80: PMAX change. Used to notify Intel(R)Dynamic Tuning Battery
participant driver when the PMAX has changed by 250mw.
0x83: PBSS change. Used to notify Intel(R) Dynamic Tuning Battery
participant driver when the power source has changed.
0x85: RBHF change. Used to notify Intel(R)Dynamic Tuning Battery
participant driver when the RBHF has changed over a threshold by
5mOhm.
0x86: Battery Capability change. Used to notify Intel(R)Dynamic Tuning
Battery participant driver when the battery capability has changed.

Srinivas Pandruvada 668ce99e4e ACPI: DPTF: Additional sysfs attributes for power participant driver
Add two additional attributes to the existing power participant driver:
rest_of_platform_power_mw: (RO) Shows the rest of worst case platform
power in mW outside of S0C. This will help in power distribution to SoC
and rest of the system. For example on a test system, this value is 2.5W
with a 15W TDP SoC. Based on the adapter rating (adapter_rating_mw), user
space software can decide on proper power allocation to SoC to improve
short term performance via powercap/RAPL interface.

prochot_confirm: (WO) Confirm EC about a prochot notification.

Also userspace is notified via sysfs_notify(), whenever power source or
rest of the platform power is changed. So user space can use poll()
system call on those attributes.

The ACPI methods used in this patch are as follows:

PROP
This object evaluates to the rest of worst case platform power in mW.
Bits:
23:0 Worst case rest of platform power in mW.

PBOK
PBOK is a method designed to provide a mechanism for OSPM to change power
setting before EC can de-assert a PROCHOT from a device. The EC may
receive several PROCHOTs, so it has a sequence number attached to PSRC
(read via existing attribute "platform_power_source"). Once OSPM takes
action for a PSRC change notification, it can call PBOK method to confirm
with the sequence number.
Bits:
3:0 Power Delivery State Change Sequence number
30  Reserved
31  0 – Not OK to de-assert PROCHOT
    1 – OK to de-assert PROCHOT

PSRC (Platform Power Source): Not new in this patch but for
documentation for new bits
This object evaluates to an integer that represents the system power
source as well as the power delivery state change sequence number.
Bits:
3:0 The current power source as an integer for AC, DC, USB, Wireless.
0 = DC, 1 = AC, 2 = USB, 3 = Wireless Charging
7:4 Power Delivery State Change Sequence Number. Default value is 0

Notifications:
0x81: (Power State Change) Used to notify when the power source has
changed.
0x84: (PROP change) Used to notify when the platform rest of power has
changed.

Bruno Meneguele 8ece3b3eb5 kernel/printk: add kmsg SEEK_CUR handling
Userspace libraries, e.g. glibc's dprintf(), perform a SEEK_CUR operation
over any file descriptor requested to make sure the current position isn't
pointing to junk due to previous manipulation of that same fd. And whenever
that fd doesn't have support for such operation, the userspace code expects
-ESPIPE to be returned.

However, when the fd in question references the /dev/kmsg interface, the
current kernel code state returns -EINVAL instead, causing an unexpected
behavior in userspace: in the case of glibc, when -ESPIPE is returned it
gets ignored and the call completes successfully, while returning -EINVAL
forces dprintf to fail without performing any action over that fd:

  if (_IO_SEEKOFF (fp, (off64_t)0, _IO_seek_cur, _IOS_INPUT|_IOS_OUTPUT) ==
  _IO_pos_BAD && errno != ESPIPE)
    return NULL;

With this patch we make sure to return the correct value when SEEK_CUR is
requested over kmsg and also add some kernel doc information to formalize
this behavior.

Pierre-Louis Bossart bcac590299 soundwire: add Slave sysfs support
Expose MIPI DisCo Slave properties in sysfs.

For Slave properties and Data Port 0, the attributes are managed with
simple devm_ support.

A Slave Device may have more than one Data Port (DPN), and each Data
Port can be sink or source. The attributes are created dynamically
using pre-canned macros, but still use devm_ with a name attribute
group to avoid creating kobjects - as requested by GregKH. In the
_show function, we use container_of() to retrieve port number and
direction required to extract the information.

Audio modes are not supported for now. Depending on the discussions
the SoundWire Device Class, we may add it later as is or follow the

In Gaudi there is a feature of clock gating certain engines.
Therefore, add this property to the device structure.

In addition, due to a limitation of this feature, the driver needs to
dynamically enable or disable this feature during run-time. Therefore, add
ASIC interface functions to enable/disable this function from the common
code.

Moreover, this feature must be turned off when the user wishes to debug the
ASIC by reading/writing registers and/or memory through the driver's

Akira Shimahara 57c76221d5 w1_therm: adding bulk read support to trigger multiple conversion on bus
Adding bulk read support:
Sending a 'trigger' command in the dedicated sysfs entry of bus master
device send a conversion command for all the slaves on the bus. The sysfs
entry is added as soon as at least one device supporting this feature
is detected on the bus.

The behavior of the sysfs reading temperature on the device is as follow:
 * If no bulk read pending, trigger a conversion on the device, wait for
 the conversion to be done, read the temperature in device RAM
 * If a bulk read has been trigger, access directly the device RAM
This behavior is the same on the 2 sysfs entries ('temperature' and
'w1_slave').

Reading the therm_bulk_read sysfs give the status of bulk operations:
 * '-1': conversion in progress on at least 1 sensor
 * '1': conversion complete but at least one sensor has not been read yet
 * '0': no bulk operation. Reading temperature on ecah device will trigger
a conversion

As not all devices support bulk read feature, it has been added in device
family structure.

The attribute is set at master level as soon as a supporting device is
discover. It is removed when the last supported device leave the bus.
The count of supported device is kept with the static counter
bulk_read_device_counter.

A strong pull up is apply on the line if at least one device required it.
The duration of the pull up is the max time required by a device on the
line, which depends on the resolution settings of each device. The strong
pull up could be adjust with the a module parameter.

state could be performed using the master search command.

As alarms temperature level are store in a 8 bit register on the device
and are signed values, a safe cast shall be performed using the min and
max temperature that device are able to measure. This is done by
int_to_short inline function.

A 'write_data' field is added in the device structure, to bind the

Akira Shimahara 67b392f7b8 w1_therm: optimizing temperature read timings
Optimizing temperature reading by reducing waiting conversion time
according to device resolution settings, as per device specification.
This is device dependent as not all the devices supports resolution
setting, so it has been added in device family structures.

The process to read the temperature on the device has been adapted in a
new function 'convert_t()', which replace the former 'read_therm()', is
introduce to deal with this timing. Strong pull up is also applied during
the required time, according to device power status needs and
'strong_pullup' module parameter.

'temperature_from_RAM()' function is introduced to get the correct
temperature computation (device dependent) from device RAM data.

An new sysfs entry has been added to ouptut only temperature. The old
entry w1_slave has been kept for compatibility, without changing its
output format.

Akira Shimahara 45d457a4cf w1_therm: adding eeprom sysfs entry
The driver implement 2 hardware functions to access device RAM:
 * copy_scratchpad
 * recall_scratchpad
They act according to device specifications.

As EEPROM operations are not device dependent (all w1_therm can perform
EEPROM read/write operation following the same protocol), it is removed
from device families structures.

Akira Shimahara 308bdb94de w1_therm: adding resolution sysfs entry
Adding resolution sysfs entry (RW) to get or set the device resolution
Write values are managed as follow:
	* '9..12': resolution to set in bit
	* Anything else: do nothing
Read values are :
	* '9..12': device resolution in bit
	* '-xx': xx is kernel error when reading the resolution

Only supported devices will show the sysfs entry. A new family has been
created for DS18S20 devices as they do not implement resolution feature.

The resolution of each device is check when the device is
discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'.
The status is stored in the device structure w1_therm_family_data so
that the driver always knows the resolution of each device, which could
be used later to determine the required conversion duration (resolution
dependent).

The resolution is re evaluate each time a user read or write the sysfs
entry.

To avoid looping through the w1_therm_families at run time, the pointer
'specific_functions' is set up to the correct 'w1_therm_family_converter'
when the slave is added (which mean when it is discovered by the master).
This initialization is done by a helper function
'device_family(struct w1_slave *sl)', and a dedicated macro
'SLAVE_SPECIFIC_FUNC(sl)' allow the access to the specific function of the
slave device.

'read_scratchpad' and 'write_scratchpad' are the hardware functions to
access the device RAM, as per protocol specification.

It cancel the former 'precision' functions, which was only set and never
read (so not stored in the device struct).

Akira Shimahara b7bb6ca17a w1_therm: adding ext_power sysfs entry
Adding ext_power sysfs entry (RO). Return the power status of the device:
 - 0: device parasite powered
 - 1: device externally powered
 - xx: xx is kernel error

The power status of each device is check when the device is
discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'.
The status is stored in the device structure w1_therm_family_data so
that the driver always knows the power state of each device, which could
be used later to determine the required strong pull up to apply on the
line.

The power status is re evaluate each time the sysfs ext_power read by
a user.

The hardware function 'read_powermode(struct w1_slave *sl)' act just as
per device specifications, sending W1_READ_PSUPPLY command on the bus,
and issue a read time slot, reading only one bit.

A helper function 'bool bus_mutex_lock(struct mutex *lock)' is introduced.
It try to aquire the bus mutex several times (W1_THERM_MAX_TRY), waiting
W1_THERM_RETRY_DELAY between two attempt.

Jithu Joseph 2d30fcdd43 platform/x86: Add Slim Bootloader firmware update signaling driver
Slim Bootloader(SBL) is a small open-source boot firmware,
designed for running on certain Intel platforms. SBL can be
thought-of as fulfilling the role of a minimal BIOS
implementation, i.e initializing the hardware and booting
Operating System.

Since SBL is not UEFI compliant, firmware update cannot be triggered
using standard UEFI runtime services. Further considering performance
impact, SBL doesn't look for a firmware update image on every reset
and does so only when firmware update signal is asserted.

SBL exposes an ACPI-WMI device which comes up in sysfs as
/sys/bus/wmi/44FADEB1xxx and this driver adds a
"firmware_update_request" device attribute. This attribute normally
has a value of 0 and userspace can signal SBL to update firmware,
on next reboot, by writing a value of 1 like:

echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request

This driver only implements a signaling mechanism, the actual firmware
update process and various details like firmware update image format,
firmware image location etc are defined by SBL and are not in the
scope of this driver.

Wu Hao 724142f8c4 fpga: dfl: fme: add performance reporting support
This patch adds support for performance reporting private feature
for FPGA Management Engine (FME). Now it supports several different
performance counters, including 'basic', 'cache', 'fabric', 'vtd'
and 'vtd_sip'. It allows user to use standard linux tools to access
these performance counters.

e.g. List all events by "perf list"

  perf list | grep fme

  dfl_fme0/cache_read_hit/                     [Kernel PMU event]
  dfl_fme0/cache_read_miss/                    [Kernel PMU event]
  ...

  dfl_fme0/fab_mmio_read/                      [Kernel PMU event]
  dfl_fme0/fab_mmio_write/                     [Kernel PMU event]
  ...

  dfl_fme0/fab_port_mmio_read,portid=?/        [Kernel PMU event]
  dfl_fme0/fab_port_mmio_write,portid=?/       [Kernel PMU event]
  ...

  dfl_fme0/vtd_port_devtlb_1g_fill,portid=?/   [Kernel PMU event]
  dfl_fme0/vtd_port_devtlb_2m_fill,portid=?/   [Kernel PMU event]
  ...

  dfl_fme0/vtd_sip_iotlb_1g_hit/               [Kernel PMU event]
  dfl_fme0/vtd_sip_iotlb_1g_miss/              [Kernel PMU event]
  ...

  dfl_fme0/clock                               [Kernel PMU event]
  ...

e.g. check increased counter value after run one application using
"perf stat" command.

 perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_mmio_write/ ./test

 Performance counter stats for './test':

                 1      dfl_fme0/fab_mmio_read/
                 2      dfl_fme0/fab_mmio_write/

       1.009496520 seconds time elapsed

Please note that fabric counters support both fab_* and fab_port_*, but
actually they are sharing one set of performance counters in hardware.
If user wants to monitor overall data events on fab_* then fab_port_*
can't be supported at the same time, see example below:

perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_port_mmio_write,portid=0/

 Performance counter stats for 'system wide':

                 0      dfl_fme0/fab_mmio_read/
   <not supported>      dfl_fme0/fab_port_mmio_write,portid=0/

Mika Westerberg 25f1ca31e2 platform/x86: intel_pmc_ipc: Convert to MFD
This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.

MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.

The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

Mark Gross 7e5b3c267d x86/speculation: Add Special Register Buffer Data Sampling (SRBDS) mitigation
SRBDS is an MDS-like speculative side channel that can leak bits from the
random number generator (RNG) across cores and threads. New microcode
serializes the processor access during the execution of RDRAND and
RDSEED. This ensures that the shared buffer is overwritten before it is
released for reuse.

While it is present on all affected CPU models, the microcode mitigation
is not needed on models that enumerate ARCH_CAPABILITIES[MDS_NO] in the
cases where TSX is not supported or has been disabled with TSX_CTRL.

The mitigation is activated by default on affected processors and it
increases latency for RDRAND and RDSEED instructions. Among other
effects this will reduce throughput from /dev/urandom.

* Enable administrator to configure the mitigation off when desired using
  either mitigations=off or srbds=off.

* Export vulnerability status via sysfs

* Rename file-scoped macros to apply for non-whitelist table initializations.

 [ bp: Massage,
   - s/VULNBL_INTEL_STEPPING/VULNBL_INTEL_STEPPINGS/g,
   - do not read arch cap MSR a second time in tsx_fused_off() - just pass it in,
