Claudiu Beznea 5d051cf94f mfd: atmel-flexcom: Use .resume_noirq
Flexcom IP embeds 3 other IPs: usart, i2c, spi and selects the operation
mode (usart, i2c, spi) via mode register (FLEX_MR). On i2c bus there might
be connected critical devices (like PMIC) which on suspend/resume should
be suspended/resumed at the end/beginning. i2c uses
.suspend_noirq/.resume_noirq for this kind of purposes. Align flexcom
to use .resume_noirq as it should be resumed before the embedded IPs.
Otherwise the embedded devices might behave badly.

Matti Vaittinen 306456c21c mfd: bd70528: Drop BD70528 support
The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

Linus Torvalds d4efc0de00 chrome platform changes for 5.16
cros_ec_typec:
 * Clean up use of cros_ec_check_features
 
 cros_ec_*:
 * Rename and move cros_ec_pd_command to cros_ec_command, and make changes to
   cros_ec_typec and cros_ec_proto to use the new common command, reducing
   duplication.
 
 sensorhub:
 * simplify getting .driver_data in cros_ec_sensors_core and cros_ec_sensorhub
 
 misc:
 * Maintainership change. Enric Balletbo i Serra has moved on from Collabora,
   so removing him from chrome/platform maintainers. Thanks for all of your
   hard work maintaining this, Enric, and best of luck to you in your new role!
 * Add Prashant Malani as driver maintainer for cros_ec_typec.c and
   cros_usbpd_notify. He was already principal contributor of these drivers.

This patch extends the DLN2 driver; adding cell for adc_dln2 module.

The original patch[1] fell through the cracks when the driver was added
so ADC has never actually been usable. That patch did not have ACPI
support which was added in v5.9, so the oldest supported version this
current patch can be backported to is 5.10.

Krzysztof Kozlowski 8163fbd971 mfd: max14577: Do not enforce (incorrect) interrupt trigger type
Interrupt line can be configured on different hardware in different way,
even inverted.  Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.

The Maxim 14577/77836 datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.

The interrupt line is shared between PMIC and charger driver, so using
level sensitive interrupt is here especially important to avoid races.
With an edge configuration in case if first PMIC signals interrupt
followed shortly after by the RTC, the interrupt might not be yet
cleared/acked thus the second one would not be noticed.

Miquel Raynal 0a1233031c mfd: ti_am335x_tscadc: Add ADC1/magnetic reader support
Introduce a new compatible that has another set of driver data,
targeting am437x SoCs with a magnetic reader instead of the
touchscreen and a more featureful set of registers.

Miquel Raynal bf0f394c7b mfd: ti_am335x_tscadc: Introduce a helper to deal with the type of hardware
One way of knowing which hardware we are dealing with is to check the
compatible string. When this must be done at several places, it's best
and certainly more clear to use a helper for that.

Introduce ti_adc_with_touchscreen() to indicate if there is a touchscreen
controller available (meaning it's an am33xx-like ADC). This helper does
not indicate if it is actually used (that is the purpose of the use_tsc
boolean).

Introducing this helper helps making a difference in the code between
what is generic to both types of ADCs and what is specific to the am33xx
hardware before introducing support for the am437x hardware.

Just checking the number of wires will soon not be enough, add a boolean

Certain checks only make sense when there is a touchscreen wired. Make
these checks explicitly depend on the presence of the touchscreen.

The error message if we cannot retrieve the clock tells us that the

touchscreen and won't change when we will introduce ADC1/magnetic reader

Miquel Raynal 3dafbe93be mfd: ti_am335x_tscadc: Reorder the initialization steps
TI AM335X TRM [1] states that most of the configuration should be set in
the control register in the first place, before actually enabling the
hardware with the subsystem enable bit.

So far only half of the configuration was made in the first step (before
enabling the "subsystem"), which does not make really sense. Also, the
probe and the resume patch were acting differently. Let's harmonize all
this by following these steps:
1/ Configure the CLKDIV register
2/ Configure the CTRL register
3/ Configure the idle configuration
4/ Really enable the device by rewriting the CTRL register with the
   subsystem enable bit set.

Merge tag 'gpio-updates-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We mostly have various improvements and refactoring all over the place
  but also some interesting new features - like the virtio GPIO driver
  that allows guest VMs to use host's GPIOs. We also have a new/old GPIO
  driver for rockchip - this one has been split out of the pinctrl
  driver.

  Summary:

   - new driver: gpio-virtio allowing a guest VM running linux to access
     GPIO lines provided by the host

   - split the GPIO driver out of the rockchip pin control driver

   - add support for a new model to gpio-aspeed-sgpio, refactor the
     driver and use generic device property interfaces, improve property
     sanitization

   - add ACPI support to gpio-tegra186

   - improve the code setting the line names to support multiple GPIO
     banks per device

   - constify a bunch of OF functions in the core GPIO code and make the
     declaration for one of the core OF functions we use consistent
     within its header

   - use software nodes in intel_quark_i2c_gpio

   - add support for the gpio-line-names property in gpio-mt7621

   - use the standard GPIO function for setting the GPIO names in
     gpio-brcmstb

   - fix a bunch of leaks and other bugs in gpio-mpc8xxx

   - use generic pm callbacks in gpio-ml-ioh

   - improve resource management and PM handling in gpio-mlxbf2

   - modernize and improve the gpio-dwapb driver

   - coding style improvements in gpio-rcar

   - documentation fixes and improvements

   - update the MAINTAINERS entry for gpio-zynq

   - minor tweaks in several drivers"

Linus Torvalds 75d6e7d9ce Nothing changed in the clk framework core this time around. We did get
some updates to the basic clk types to use determine_rate for the
 divider type and add a power of two fractional divider flag though.
 Otherwise, this is a collection of clk driver updates. More than half
 the diffstat is in the Qualcomm clk driver where we add a bunch of data
 to describe clks on various SoCs and fix bugs. The other big new thing
 in here is the Mediatek MT8192 clk driver. That's been under review for
 a while and it's nice to see that it's finally upstream.
 
 Beyond that it's the usual set of minor fixes and tweaks to clk drivers.
 There are some non-clk driver bits in here which have all been acked by
 the respective maintainers.
 
 New Drivers:
  - Support video, gpu, display clks on qcom sc7280 SoCs
  - GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
  - Multimedia clks (MMCC) on qcom MSM8994/MSM8992
  - RPMh clks on qcom SM6350 SoCs
  - Support for Mediatek MT8192 SoCs
  - Add display (DU and DSI) clocks on Renesas R-Car V3U
  - Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
    resets on Renesas RZ/G2L
 
 Updates:
  - Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
  - Add power of two flag to fractional divider clk type
  - Migrate some clk drivers to clk_divider_ops.determine_rate
  - Migrate to clk_parent_data in gcc-sdm660
  - Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2
  - Switch from .round_rate to .determine_rate in clk-divider-gate
  - Fix clock tree update for TF-A controlled clocks for all i.MX8M
  - Add missing M7 core clock for i.MX8MN
  - YAML conversion of rk3399 clock controller binding
  - Removal of GRF dependency for the rk3328/rk3036 pll types
  - Drop CLK_IS_CRITICAL flag from Tegra fuse clk
  - Make CLK_R9A06G032 Kconfig symbol invisible
  - Convert various DT bindings to YAML

Linus Torvalds ebf435d3b5 IIO / Staging driver update for 5.15-rc1
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae0 ("staging: r8188eu: remove rtw_ioctl

  End result: the merge resolution was to throw all of that away,

Linus Torvalds c6c3c5704b Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
 
 These do change a number of different things across different
 subsystems, and because of that, there were 2 stable tags created that
 might have already come into your tree from different pulls that did the
 following
 	- changed the bus remove callback to return void
 	- sysfs iomem_get_mapping rework
 
 The latter one will cause a tiny merge issue with your tree, as there
 was a last-minute fix for this in 5.14 in your tree, but the fixup
 should be "obvious".  If you want me to provide a fixed merge for this,
 please let me know.
 
 Other than those two things, there's only a few small things in here:
 	- kernfs performance improvements for huge numbers of sysfs
 	  users at once
 	- tiny api cleanups
 	- other minor changes
 
 All of these have been in linux-next for a while with no reported
 problems, other than the before-mentioned merge issue.

Lee Jones c753ea3178 mfd: simple-mfd-i2c: Add support for registering devices via MFD cells
More devices are cropping up requiring only Regmap initialisation and
child registration functionality.  We currently only support that if
all required devices are represented by their own Device Tree nodes
complete with compatible strings.

However, not everyone is happy with adding empty nodes that provide no
additional device information into the Device Tree.

Rather than have a plethora of mostly empty, function-less drivers in
MFD, we'll support those simple cases in here instead via MFD cells.

Linus Walleij f28fd3b6f7 mfd/cpuidle: ux500: Rename driver symbol
The PRCMU driver defines this as a DT node but there are no bindings
for it and it needs no data from the device tree. Just spawn the
device directly in the same way as the watchdog.

Name it "db8500-cpuidle" since there are no ambitions to support any
more SoCs than this one.

This rids this annoying boot message:
[    0.032610] cpuidle-dbx500: Failed to locate of_node [id: 0]

However I think the device still spawns and work just fine, despite
not finding a device tree node.

Emil Renner Berthing 72b89b9ab5 mfd: tps65086: Add cell entry for reset driver
The only way to reset the BeagleV Starlight v0.9 board[1] properly is to
tell the PMIC to reset itself which will then assert the external reset
lines of the SoC, USB hub and ethernet phy.

This adds an mfd cell entry for the reset driver doing just that.

Hans de Goede 32679a7a6b mfd: axp20x: Add supplied-from property to axp288_fuel_gauge cell
The power-supply framework has the notion of one power-supply device
being supplied by another. A typical example of this is a charger
charging a battery.

A tablet getting plugged in to charge (or plugged out) only results in
events seen by the axp288_charger device / MFD cell. Which means that
a change udev-event only gets send for the charger power-supply class
device, not for the battery (the axp288_fuel_gauge device).

The axp288_fuel_gauge does have an external_power_change'd callback
which will generate a change udev-event when called. But before this
commit this never got called because the power-supply core only calls
this when a power-supply class device's supplier changes and the
supplier link from axp288_charger to axp288_fuel_gauge was missing.

Add a "supplied-from" property to axp288_fuel_gauge cell, pointing
to the "axp288_charger" power-supply class device, so that the
axp288_fuel_gauge's external_power_change'd callback gets called on
axp288_charger state changes.

Uwe Kleine-König fc7a6209d5 bus: Make remove callback return void
The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.

This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.

With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

Hans de Goede f949a9ebce mfd: axp20x: Update AXP288 volatile ranges
On Cherry Trail devices with an AXP288 PMIC the external SD-card slot
used the AXP's DLDO2 as card-voltage and either DLDO3 or GPIO1LDO
(GPIO1 pin in low noise LDO mode) as signal-voltage.

These regulators are turned on/off and in case of the signal-voltage
also have their output-voltage changed by the _PS0 and _PS3 power-
management ACPI methods on the MMC-controllers ACPI fwnode as well as
by the _DSM ACPI method for changing the signal voltage.

The AML code implementing these methods is directly accessing the
PMIC through ACPI I2C OpRegion accesses, instead of using the special
PMIC OpRegion handled by drivers/acpi/pmic/intel_pmic_xpower.c .

This means that the contents of the involved PMIC registers can change
without the change being made through the regmap interface, so regmap
should not cache the contents of these registers.

Mark the regulator power on/off, the regulator voltage control and the
GPIO1 control registers as volatile, to avoid regmap caching them.

Specifically this fixes an issue on some models where the i915 driver
toggles another LDO using the same on/off register on/off through
MIPI sequences (through intel_soc_pmic_exec_mipi_pmic_seq_element())
which then writes back a cached on/off register-value where the
card-voltage is off causing the external sdcard slot to stop working
when the screen goes blank, or comes back on again.

The regulator register-range now marked volatile also includes the
buck regulator control registers. This is done on purpose these are
normally not touched by the AML code, but they are updated directly
by the SoC's PUNIT which means that they may also change without going
through regmap.

Note the AXP288 PMIC is only used on Bay- and Cherry-Trail platforms,
so even though this is an ACPI specific problem there is no need to
make the new volatile ranges conditional since these platforms always
use ACPI.

Linus Torvalds d6b63b5b7d sound updates for 5.14
As the diffstat scatters over the tree, we've got many tree-wide
 small changes, but also got quite a few intrusive changes in the
 core side.  The only ABI-visible core change is the new rawmidi
 framing mode support while others are kernel-internal, mostly code
 refactoring and/or nice improvements.
 
 Here are some highlights:
 
 Core:
 - A new framing access mode for rawmidi to get timestamps
 - Cleanup / refactoring of buffer memory management helper code
 - Support for automatic negotiation of ASoC DAI formats
 - Revival of software suspend for PCM and control core, as a
   preliminary work for PCI BAR rescan support
 
 ASoC:
 - Accessory detection support for several Qualcomm parts
 - Support for IEC958 control with hdmi-codec
 - Merging of Tegra machine drivers into a single driver
 - Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP
   i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm
   Quinary MI2S, Texas Instruments TAS2505
 
 USB-audio:
 - Reduction of latency at playback start
 - Code cleanup / fixes of usx2y driver
 - Scarlett2 mixer code fixes and enhancements
 - Quirks for Ozone and Denon devices
 
 HD-audio:
 - A few quirks for HP and ASUS machines
 - Display power management fixes
 
 Others:
 - FireWire code refactoring and enhancements
 - Tree-wide trivial coding-style fixes

Linus Torvalds 21edf50948 Updates for the interrupt subsystem:
Core changes:
 
   - Cleanup and simplification of common code to invoke the low level
     interrupt flow handlers when this invocation requires irqdomain
     resolution. Add the necessary core infrastructure.
 
   - Provide a proper interface for modular PMU drivers to set the
     interrupt affinity.
 
   - Add a request flag which allows to exclude interrupts from spurious
     interrupt detection. Useful especially for IPI handlers which always
     return IRQ_HANDLED which turns the spurious interrupt detection into a
     pointless waste of CPU cycles.
 
 Driver changes:
 
   - Bulk convert interrupt chip drivers to the new irqdomain low level flow
     handler invocation mechanism.
 
   - Add device tree bindings for the Renesas R-Car M3-W+ SoC
 
   - Enable modular build of the Qualcomm PDC driver
 
   - The usual small fixes and improvements.

   - Add a request flag which allows to exclude interrupts from spurious
     interrupt detection. Useful especially for IPI handlers which
     always return IRQ_HANDLED which turns the spurious interrupt
     detection into a pointless waste of CPU cycles.

  Driver changes:

   - Bulk convert interrupt chip drivers to the new irqdomain low level
     flow handler invocation mechanism.

   - Add device tree bindings for the Renesas R-Car M3-W+ SoC

   - Enable modular build of the Qualcomm PDC driver

   - The usual small fixes and improvements"

Hans de Goede 33d550701b mfd: arizona: Allow building arizona MFD-core as module
There is no reason why the arizona core,irq and codec model specific
regmap bits cannot be build as a module. All they do is export symbols
which are used by the arizona-spi/i2c and arizona-codec modules, which
themselves can be built as module.

Change the Kconfig and Makefile arizona bits so that the arizona MFD-core
can be built as a module.

This is especially useful on x86 platforms with a WM5102 codec, this
allows the arizona MFD driver necessary for the WM5102 codec to be
enabled in generic distro-kernels without growing the base kernel-image
size.

Note this also adds an explicit "depends on MFD_ARIZONA" to all the
arizona codec Kconfig options. The codec drivers use functions from mfd
arizona-core. These new depends are necessary to disallow the codec
drivers being builtin when the arizona-core is build as a module,
otherwise we end up with missing symbol errors when building vmlinuz.

Andre Przywara 3efc465f91 mfd: axp20x: Allow AXP 806 chips without interrupt lines
Currently the AXP chip requires to have its IRQ line connected to some
interrupt controller, and will fail probing when this is not the case.

On a new Allwinner SoC (H616) there is no NMI pin anymore, and at
least one board does not connect the AXP's IRQ pin to anything else,
so the interrupt functionality of the AXP chip is simply not available.

Check whether the interrupt line number returned by the platform code is
valid, before trying to register the irqchip. If not, we skip this
registration, to avoid the driver to bail out completely.
Also we need to skip the power key functionality, as this relies on
a valid IRQ as well.

cause. With this fixing, the name field in struct regmap_debugfs_node
is removed. When initialize debugfs for syscon driver, the name
field of struct regmap_config is not used anymore. So, the allocated
name field of struct regmap_config is need to be freed directly after
regmap initialization to avoid memory leak.

Some pmics of the mt6397 family (such as MT6358), have two IRQs per
physical key: one for press event, another for release event.

The mtk-pmic-keys driver assumes that each key only has one
IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping.

This won't work for MT6358, as we have multiple resources (2) for one key.

To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name
instead of by index.

Note: The keys_resources are not part of the device-tree bindings so
this won't break any DT schemas.

Linus Torvalds 47080f2286 hwmon updates for v5.13
The most notable change is the removal of the amd_energy driver. It was
 rendered all but unusable by making its attributes privileged-only to work
 around a security issue. A suggested remedy was rejected by AMD, so the
 only real solution was to remove the driver. For the future, we'll have
 to make sure that no privileged-access-only drivers are accepted into the
 hwmon subsystem in the first place. The hwmon ABI document was updated
 accordingly.
 
 Other changes:
 
 PMBus drivers:
 - Added driver for MAX15301
 - Added driver for BluTek BPA-RS600
 - Added driver for fsp-3y PSUs and PDUs
 - Added driver for Infineon IR36021
 - Added driver for ST STPDDC60
 - Added support for TI TPS53676 to tps53679 driver
 - Introduced PMBUS symbol namespace
   This was made necessary by a suggestion to use its exported functions
   from outside the hwmon subsystem.
 - Minor improvements and bug fixes
 
 New drivers:
 - Driver for NZXT Kraken X42/X52/X62/X72
 
 Driver enhancements:
 - Added support for Intel D5005 to intel-m10-bmc-hwmon driver
 - Added support for NCT6686D to nct6683 driver
 
 Other:
 - Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
 - Added support for fan drawers capability and present registers to mlxreg-fan
   driver
 - Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
 - Replaced snprintf in show functions with sysfs_emit
   Done with coccinelle script for all drivers to preempt endless per-driver
   submissions of the same change.
 - Use kobj_to_dev()
   Another coccinelle based change to preempt endless per-driver submissions
   of the same change.
 - Various minor fixes and improvements

 OMAP:
  - Preparation to use devicetree for genpd
  - ti-sysc needs iorange check improved when the interconnect target module
    has no control registers listed
  - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
    issues with missing resources and unnecessary deferred probe
  - ti-sysc debug option can now detect more devices
  - ti-sysc now warns if an old incomplete devicetree data is found as we
    now rely on it being complete for am3 and 4
  - soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
  - omap-prm driver needs to enable autoidle retention support for omap4
  - omap5 clocks are missing gpmc and ocmc clock registers
  - pci-dra7xx now needs to use builtin_platform_driver instead of using
    builtin_platform_driver_probe for deferred probe to work
 
 Raspberry Pi:
  - Fix-up all RPi firmware drivers so as for unbind to happen in an
    orderly fashion
  - Support for RPi's PoE hat PWM bus
 
 Qualcomm
  - Improved detection for SCM calling conventions

The driver can provide a software node group instead of

the legacy platform data structures along with unifying
a child device driver to use same interface for all
property providers, i.e. Device Tree, ACPI, and board files.

Andy Shevchenko 922e8ce883 mfd: lpc_sch: Partially revert "Add support for Intel Quark X1000"
The IRQ support for SCH GPIO is not specific to the Intel Quark SoC.
Moreover the IRQ routing is quite interesting there, so while it's
needs a special support, the driver haven't it anyway yet.

Due to above remove basically redundant code of IRQ support.

This reverts commit ec689a8a81.

Dinghao Liu fe6df2b480 mfd: arizona: Fix rumtime PM imbalance on error
pm_runtime_get_sync() will increase the rumtime PM counter
even it returns an error. Thus a pairing decrement is needed
to prevent refcount leak. Fix this by replacing this API with
pm_runtime_resume_and_get(), which will not change the runtime
PM counter on error.

While at it, amend a note comment, since usage of _ADR is found on other
platforms and tables than Intel Galileo Gen 2, in particular USB wired devices
are using it, according to Microsoft specifications for embedded platforms.

Andy Shevchenko 6dac44c602 mfd: intel_quark_i2c_gpio: Don't play dirty trick with const
As Linus rightfully noticed, the driver plays dirty trick with const,
i.e. it assigns a place holder data structure to the const field
in the MFD cell and then drops the const by explicit casting. This is
not how it should be.

Assign local pointers of the cell and resource to the respective
non-const place holders in the intel_quark_i2c_setup() and
intel_quark_gpio_setup().

Add the version of the EC in the Tolino Shine 2 HD
to the supported versions. It seems not to have an RTC
and does not ack data written to it.
The vendor kernel happily ignores write errors, using
I2C via userspace i2c-set also shows the error.
So add a quirk to ignore that error.

PWM can be successfully configured despite of that error.

Fabrice Gasnier 4917e498c6 mfd: stm32-timers: Avoid clearing auto reload register
The ARR register is cleared unconditionally upon probing, after the maximum
value has been read. This initial condition is rather not intuitive, when
considering the counter child driver. It rather expects the maximum value
by default:
- The counter interface shows a zero value by default for 'ceiling'
  attribute.
- Enabling the counter without any prior configuration makes it doesn't
  count.

The reset value of ARR register is the maximum. So Choice here
is to backup it, and restore it then, instead of clearing its value.
It also fixes the initial condition seen by the counter driver.
