By default, ina3221, as a hardware monitor, continuously measures
the inputs and generates corresponding data. However, for battery
powered devices, this mode might be power consuming.
The DT binding doc is updated with a new boolean type property to
allow changing the default operating mode from consuming mode to
single-shot mode, which will measure input on demand and then shut
down to save power.
So this patch implements the DT property accordingly.

Fix tps53679_probe() by using dynamically allocated "pmbus_driver_info"
structure instead of static. Usage of static structures causes
overwritten of the field "vrm_version", in case the system is equipped
with several tps53679 devices with the different "vrm_version".
In such case the last probed device overwrites this field for all
others.

The Kconfig lexer supports special characters such as '.' and '/' in
the parameter context. In my understanding, the reason is just to
support bare file paths in the source statement.
I do not see a good reason to complicate Kconfig for the room of
ambiguity.
The majority of code already surrounds file paths with double quotes,
and it makes sense since file paths are constant string literals.
Make it treewide consistent now.

If all three channels are disabled via in[123]_enable ABI,
the driver could suspend the chip for power saving purpose.
So this patch adds the PM runtime support in order to gain
more power control than system suspend and resume use case.
For PM runtime, there are a few related changes happening:
1) Added a new pm_dev device pointer for all the PM runtime
callbacks. This is because hwmon core registers a child
device for each hwmon driver and passes it back to each
driver. So there might be a mismatch between two device
pointers in the driver if mixing using them.
2) Added a check in ina3221_is_enabled() to make sure that
the chip is resumed.
3) Bypassed the unchanged status in ina3221_write_enable()
in order to keep the PM runtime refcount being matched.
4) Removed the reset routine in the probe() by calling the
resume() via pm_runtime_get_sync() instead, as they're
similar. It's also necessary to do so to match initial
PM refcount with the number of enabled channels.

The data might need some time to get ready after channel enabling,
although the data register is always readable. The CVRF bit is to
indicate that data conversion is finished, so polling the CVRF bit
before data reading could ensure the result being valid.
An alternative way could be to wait for expected time between the
channel enabling and the data reading. And this could avoid extra
I2C communications. However, INA3221 seemly takes longer time than
what's stated in the datasheet. Test results show that sometimes
it couldn't finish data conversion in time.
So this patch plays safe by adding a CVRF polling to make sure the
data register is updated with the new data.

This change adds a mutex to serialize accesses of sysfs attributes.
This is required when polling CVRF bit of the MASK/ENABLE register
because this bit is cleared on a read of this MASK/ENABLE register
or a write to CONFIG register, which means that this bit might be
accidentally cleared by reading other fields like alert flags.
So this patch adds a mutex lock to protect the write() and read()
callbacks. The read_string() callback won't need the lock since it
just returns the label without touching any hardware register.

There is nothing critically wrong to read these two attributes
without having a is_enabled() check at this point. But reading
the MASK_ENABLE register would clear the CVRF bit according to
the datasheet. So it'd be safer to fence for disabled channels
in order to add pm runtime feature.

The OCC is a device embedded on a POWER processor that collects and
aggregates sensor data from the processor and system. The OCC can
provide the raw sensor data as well as perform thermal and power
management on the system.
This driver provides a hwmon interface to the OCC from a service
processor (e.g. a BMC). The driver supports both POWER8 and POWER9 OCCs.
Communications with the POWER8 OCC are established over standard I2C
bus. The driver communicates with the POWER9 OCC through the FSI-based
OCC driver, which handles the lower-level communication details.
This patch lays out the structure of the OCC hwmon driver. There are two
platform drivers, one each for P8 and P9 OCCs. These are probed through
the I2C tree and the FSI-based OCC driver, respectively. The patch also
defines the first common structures and methods between the two OCC
versions.

When using DT configurations, the id pointer might turn out to
be NULL. Then the driver encounters NULL pointer access:
Unable to handle kernel read from unreadable memory at vaddr 00000018
[...]
PC is at ina2xx_probe+0x114/0x200
LR is at ina2xx_probe+0x10c/0x200
[...]
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
The reason is that i2c core returns the id pointer by matching
id_table with client->name, while the client->name is actually
using the name from the first string in the DT compatible list,
not the best one. So i2c core would fail to match the id_table
if the best matched compatible string isn't the first one, and
then would return a NULL id pointer.
This probably should be fixed in i2c core. But it doesn't hurt
to make the driver robust. So this patch fixes it by using the
"chip" that's added to unify both DT and non-DT configurations.
Additionally, since id pointer could be null, so as id->name:
ina2xx 10-0047: power monitor (null) (Rshunt = 1000 uOhm)
ina2xx 10-0048: power monitor (null) (Rshunt = 10000 uOhm)
So this patch also fixes NULL name pointer, using client->name
to play safe and to align with hwmon->name.

Devices with compatible="pmbus" field have zero initial page count,
and pmbus_clear_faults() being called before the page count auto-
detection does not actually clear faults because it depends on the
page count. Non-cleared faults in its turn may fail the subsequent
page count auto-detection.
This patch fixes this problem by calling pmbus_clear_fault_page()
for currently set page and calling pmbus_clear_faults() after the
page count was detected.

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

Trace events are useful for people who collect data from the
Ftrace outputs. There're people who analyse the relationship
of cpufreq, thermal and hwmon (power/voltage/current) using
the convenient and timestamped Ftrace outputs, while unlike
cpufreq and thermal subsystems the hwmon does not have trace
events supported yet.
So this patch adds initial trace events for the hwmon core.
To call hwmon_attr_base() for aligned attr index numbers, it
also moves the function upward.
Ftrace outputs:
...: hwmon_attr_show_string: index=2, attr_name=in2_label, val=VDD_5V
...: hwmon_attr_show: index=2, attr_name=in2_input, val=5112
...: hwmon_attr_show: index=2, attr_name=curr2_input, val=440
Note that the _attr_show and _attr_store functions are tied
to the _with_info API. So a hwmon driver requiring the trace
events feature should use _with_info API to register a hwmon
device.

An ina3221 chip has three input ports. Each port is used
to measure the voltage and current of its input source.
The DT binding now has defined bindings for their input
sources, so the driver should read these information and
handle accordingly.
This patch adds a new structure of input source specific
information including input source label, shunt resistor
value and its connection status. It exposes these labels
via in[123]_label sysfs nodes upon available, and also
disables those channels where there are no input source
being connected. Meanwhile, it also adds in[123]_enable
sysfs nodes for users to get control of three channels,
and returns -ENODATA code for any sensor read according
to hwmon ABI.

The MODE3-1 bits are located at BIT 2-0 according to the datasheet.

The MSB (15th bit) of INA3221_CONFIG is a self-clear reset bit.
So this register should be added to the volatile_table of the
regmap_config. Otherwise, we will see this bit is sticky in the
regcache which might accidentally reset the chip when an actual
write happens to the register.
This might not be a severe bug for the current code line since
there's no second place touching the INA3221_CONFIG except the
reset routine in the probe().

Technically this is not required because disabling the PWM should be
enough. However, when support for atomic operations was implemented in
the PWM subsystem, only actual changes to the PWM channel are applied
during pwm_config(), which means that during after resume from suspend
the old settings won't be applied.
One possible solution is for the PWM driver to implement its own PM
operations such that settings from before suspend get applied on resume.
This has the disadvantage of completely ignoring any particular ordering
requirements that PWM user drivers might have, so it is best to leave it
up to the user drivers to apply the settings that they want at the
appropriate time.
Another way to solve this would be to read back the current state of the
PWM at the time of resume. That way, in case the configuration was lost
during suspend, applying the old settings in PWM user drivers would
actually get them applied because they differ from the current settings.
However, not all PWM drivers support reading the hardware state, and not
all hardware may support it.
The best workaround at this point seems to be to let PWM user drivers
tell the PWM subsystem that the PWM is turned off by, in addition to
disabling it, also setting the duty cycle to 0. This causes the resume
operation to apply a configuration that is different from the current
configuration, resulting in the proper state from before suspend getting
restored.

A recent version of the datasheet lists temperature source 11 as reserved.
However, an older version of the datasheet lists temperature sources 10
and 11 as supported virtual temperature sources. Apparently the older
version of the datasheet is correct, so list those temperature sources
as supported.
Virtual temperature sources are different than other temperature sources:
Values are not read from a temperature sensor, but written either from
BIOS or an embedded controller. As such, each virtual temperature has to
be reported. Since there is now more than one temperature source, we have
to keep virtual temperature sources in a chip-specific mask and can no
longer rely on the assumption that there is only one virtual temperature
source with a fixed index. This accounts for most of the complexity of this
patch.

Not all fans have a fan pulse register. This can result in reading
beyond the end of REG_FAN_PULSES and FAN_PULSE_SHIFT arrays,
and was reported by smatch as possible error.
1672 for (i = 0; i < ARRAY_SIZE(data->rpm); i++) {
^^^^^^^^^^^^^^^^^^^^^^^^
This is a 7 element array.
...
1685 data->fan_pulses[i] =
1686 (nct6775_read_value(data, data->REG_FAN_PULSES[i])
1687 >> data->FAN_PULSE_SHIFT[i]) & 0x03;
^^^^^^^^^^^^^^^^^^^^^^^^
FAN_PULSE_SHIFT is either 5 or 6
elements.
To fix the problem, we have to ensure that all REG_FAN_PULSES and
FAN_PULSE_SHIFT have the appropriate length, and that REG_FAN_PULSES
is only read if the register actually exists.

Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.
Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

The raspberrypi-hwmon driver doesn't automatically load, although it does work
when loaded, by adding the alias it auto loads as expected when built as a

val can be indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:

spectre issue 'data->temp_src' [r]
Fix this by sanitizing val before using it to index data->temp_src
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

The adt7475_update_device() function returns error pointers. The
problem is that in show_pwmfreq() we dereference it before the check.
And then in pwm_use_point2_pwm_at_crit_show() there isn't a check at
all. I don't know if it's required, but it silences a static checker
warning and it's doesn't hurt anything to check.

Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

I2C SMBus sometimes returns error codes.
In the error case, measurement values are updated incorrectly.
The sensor application then generates warning log messages and SNMP traps.
To prevent this, add error handling into the update functions.

So let's change it to bool.

All announced Threadripper 29xx models have a temperature offset of
27 degrees C. Simplify temperature offset table to match all 29xx
Threadripper models with a single entry. Also simplify the table to match
all 19xx Threadripper models with a single entry. This effectively drops
entries for Threadripper 1910/1920/1950 which never saw the light of day.

OPAL firmware provides the facility for some groups of sensors to be
enabled/disabled at runtime to give the user the option of using the
system resources for collecting these sensors or not.
For example, on POWER9 systems, the On Chip Controller (OCC) gathers
various system and chip level sensors and maintains their values in
main memory.
This patch provides support for enabling/disabling the sensor groups
like power, temperature, current and voltage.

for 4.19, please pull the following:
- Doug updates the low-level suspend/resume code for ARM SoCs to support
the latest rev B3.0 memory controllers found on newer chips with an
appropriate match structure to perform the correct entry sequencing
- Florian updates the Device Tree binding document for these memory
controllers to list all possible compatible strings that exist given
the supported memory controllers.
- Stefan adds the GET_THROTTLED firmware property value that is required
for the Rasperry Pi voltage monitoring driver and updates the
Raspberry Pi firmware driver accordingly to register such a device
using the HWMON subsystem. Finally he adds support for reporting under
voltage conditions using a specialized HWMON driver.

Currently there is no easy way to detect undervoltage conditions on a
remote Raspberry Pi. This hwmon driver retrieves the state of the
undervoltage sensor via mailbox interface. The handling based on
Noralf's modifications to the downstream firmware driver. In case of
an undervoltage condition only an entry is written to the kernel log.

Driver obtains PWM and tachometers registers location according to the
system configuration and creates FAN/PWM hwmon objects and a cooling
device. PWM and tachometers are controlled through the on-board
programmable device, which exports its register map. This device could be
attached to any bus type, for which register mapping is supported. Single
instance is created with one PWM control, up to 12 tachometers and one
cooling device. It could be as many instances as programmable device
supports.
Currently driver will be activated from the Mellanox platform driver:
drivers/platform/x86/mlx-platform.c.
For the future ARM based systems it could be activated from the ARM
platform module.

#included header file in the Linux kernel. It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.
4146 #include <linux/platform_device.h>
After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>

Commit cc66b30382 ("hwmon: (nct6775) Rework temperature source and label
handling") changed a loop limit from "data->temp_label_num - 1" to "32",
as part of moving from a string array to a bit mask. This results in the
following error, reported by UBSAN.
UBSAN: Undefined behaviour in drivers/hwmon/nct6775.c:4179:27
shift exponent 32 is too large for 32-bit type 'long unsigned int'
Similar to the original loop, the limit has to be one less than the
number of bits.
