The driver updates seem larger this time around, with changes
is many of the SoC specific drivers, both the custom drivers/soc
ones and the closely related subsystems (memory, bus, firmware,
reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and
power management code. This is the latest variant of one of the
oldest still supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in many
of their drivers to add more features and additional SoC support. Most
of these are somewhat firmware related as the platform has a number of
firmware based interfaces to the kernel. A notable addition here is the
inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly cleanups.
The Arm SCMI firmware driver gets a major rework to modularize
the existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a
number of smaller updates.
The Arm FF-A firmware driver gets a feature update to support
the v1.2 version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring
for Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
mediatek) drivers and their DT bindings.

Pull thermal control updates from Rafael Wysocki:
"These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce
bloat
The most significant piece of this work is a change of the code
related to binding cooling devices to thermal zones which, among other
things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler
There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise
the thermal core functionality. It is expected to be used for
implementing thermal core self tests in the future
Apart from the above, there are assorted thermal driver updates

The panasonic laptop code in various places uses the SINF array with index
values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array
is big enough.
Not all panasonic laptops have this many SINF array entries, for example
the Toughbook CF-18 model only has 10 SINF array entries. So it only
supports the AC+DC brightness entries and mute.
Check that the SINF array has a minimum size which covers all AC+DC
brightness entries and refuse to load if the SINF array is smaller.
For higher SINF indexes hide the sysfs attributes when the SINF array
does not contain an entry for that attribute, avoiding show()/store()
accessing the array out of bounds and add bounds checking to the probe()
and resume() code accessing these.

Allow to disable ACPI PM Timer on suspend and enable on resume. A
disabled timer helps optimise power consumption when the system is
suspended. On resume the timer is only reactivated if it was activated
prior to suspend, so unless the ACPI PM timer is enabled in the BIOS,
this won't change anything.
The ACPI PM timer is used by Intel's iTCO/wdat_wdt watchdog to drive the
watchdog, so it doesn't need to run during suspend.

In case of error in build_tokens_sysfs(), all the memory that has been
allocated is freed at end of this function. But then free_group() is
called which performs memory deallocation again.
Also, instead of free_group() call, there should be exit_dell_smbios_smm()
and exit_dell_smbios_wmi() calls, since there is initialization, but there
is no release of resources in case of an error.
Fix these issues by replacing free_group() call with

When it is placed on the secondary display to connect via USB, it emits

reflect the user's true intention.

Make the acerhdf driver use the .should_bind() thermal zone
callback to provide the thermal core with the information on whether or
not to bind the given cooling device to the given trip point in the
given thermal zone. If it returns 'true', the thermal core will bind
the cooling device to the trip and the corresponding unbinding will be
taken care of automatically by the core on the removal of the involved
thermal zone or cooling device.
The previously existing acerhdf_bind() function bound cooling devices
to thermal trip point 0 only, so the new callback needs to return 'true'
for trip point 0. However, it is straightforward to observe that trip
point 0 is an active trip point and the only other trip point in the
driver's thermal zone is a critical one, so it is sufficient to return
'true' from that callback if the type of the given trip point is
THERMAL_TRIP_ACTIVE.

The dell-uart-backlight driver supports backlight control on Dell All In
One (AIO) models using a backlight controller board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
Now the first AIO has turned up which has not only the DSDT bits for this,
but also an actual controller attached to the UART, yet it is not using
this controller for backlight control.
Use the acpi_video_get_backlight_type() function from the ACPI video-detect
code to check if the dell-uart-backlight driver should actually be used.
This allows reusing the existing ACPI video-detect infra to override
the backlight control method on the commandline or with DMI quirks.

There is a small window in ssam_serial_hub_probe() where the controller
is initialized but has not been started yet. Specifically, between
ssam_controller_init() and ssam_controller_start(). Any failure in this
window, for example caused by a failure of serdev_device_open(),
currently results in an incorrect warning being emitted.
In particular, any failure in this window results in the controller
being destroyed via ssam_controller_destroy(). This function checks the
state of the controller and, in an attempt to validate that the
controller has been cleanly shut down before we try and deallocate any
resources, emits a warning if that state is not SSAM_CONTROLLER_STOPPED.
However, since we have only just initialized the controller and have not
yet started it, its state is SSAM_CONTROLLER_INITIALIZED. Note that this
is the only point at which the controller has this state, as it will
change after we start the controller with ssam_controller_start() and
never revert back. Further, at this point no communication has taken
place and the sender and receiver threads have not been started yet (and
we may not even have an open serdev device either).
Therefore, it is perfectly safe to call ssam_controller_destroy() with a
state of SSAM_CONTROLLER_INITIALIZED. This, however, means that the
warning currently being emitted is incorrect. Fix it by extending the
check.

Given that two devices marks the start of a trend, this patch also adds

Calling VPC commands consists of several VPCW and VPCR ACPI calls.
These calls and their results can get mixed up if they are called
simultaneously from different threads, like acpi notify handler,
sysfs, debugfs, notification chain.
The commit e2ffcda162 ("ACPI: OSL: Allow Notify () handlers to run on
all CPUs") made the race issues much worse than before it but some
races were possible even before that commit.
Add a mutex to synchronize VPC commands.

Some models need to trigger the EC after each YMC event for the yoga
mode control to work properly. EC triggering consist of a VPC call from
the lenovo-ymc module. Except for this, all VPC calls are in the
ideapad-laptop module.
Since ideapad-laptop has a notification chain, a new YMC_EVENT action
can be added and triggered from the lenovo-ymc module. Then the
ideapad-laptop can trigger the EC.
If the triggering is in the ideapad-laptop module, then the ec_trigger
module parameter should be there as well.
Move the ymc_trigger_ec functionality and the ec_trigger module
parameter to the ideapad-laptop module.

If the Ambient Light Sensor (ALS) is disabled, the current code in the PMF
driver does not query for Human Presence Detection (HPD) data in
amd_pmf_get_sensor_info(). As a result, stale HPD data is used by PMF-TA
to evaluate policy conditions, leading to unexpected behavior in the policy
output actions.
To resolve this issue, modify the PMF driver to query HPD data
independently of ALS.
Since user_present is a boolean, modify the current code to return true if
the user is present and false if the user is away or if the sensor is not
detected, and report this status to the PMF TA firmware accordingly.
With this change, amd_pmf_get_sensor_info() now returns void instead of
int.
