772cbba5a8 platform/x86: x86-android-tablets: Add support for the Dolby button on Peaq C1010
The Peaq C1010 tablet has a special "Dolby" button. This button has
a WMI interface, but this is broken in several ways:

1. It only supports polling
2. The value read on polling goes from 0 -> 1 for one poll on both edges
   of the button, with no way to tell which edge causes the poll to
   return 1.
3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID).

There currently is a WMI driver for this, but it uses several kludges
to work around these issues and is not entirely reliable due to 2.

Replace the unreliable WMI driver by using the x86-android-tablets code
to instantiate a gpio_keys device for this.

The Acer Iconia One 7 B1-750 is a x86 ACPI tablet which ships with Android
x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there, causing various resource conflicts. Enumeration of these
is skipped through the acpi_quirk_skip_i2c_client_enumeration().

Add support for manually instantiating the I2C + other devices which are
actually present on this tablet by adding the necessary device info to
the x86-android-tablets module.

REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

Therefore, change the use of "depends on REGMAP" to "select REGMAP".

 There's a lot of changes this development cycle, most of the work falls
 into two different categories:
   - fw_devlink fixes and updates.  This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.
   - driver core changes to work to make struct bus_type able to be moved
     into read-only memory (i.e. const)  The recent work with Rust has
     pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only making
     things safer overall.  This is the contuation of that work (started
     last release with kobject changes) in moving struct bus_type to be
     constant.  We didn't quite make it for this release, but the
     remaining patches will be finished up for the release after this
     one, but the groundwork has been laid for this effort.
 
 Other than that we have in here:
   - debugfs memory leak fixes in some subsystems
   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.
   - cacheinfo rework and fixes
   - Other tiny fixes, full details are in the shortlog
 
 All of these have been in linux-next for a while with no reported
 problems.

1b72607d73 Thermal control updates for 6.3-rc1
- Rework a large bunch of drivers to use the generic thermal trip
    structure and use the opportunity to do more cleanups by removing
    unused functions from the OF code (Daniel Lezcano).
 
  - Remove core header inclusion from drivers (Daniel Lezcano).
 
  - Fix some locking issues related to the generic thermal trip rework
    (Johan Hovold).
 
  - Fix a crash when requesting the critical temperature on tegra, which
    is related to the generic trip point work (Jon Hunter).
 
  - Clean up thermal device unregistration code (Viresh Kumar).
 
  - Fix and clean up thermal control core initialization error code
    paths (Daniel Lezcano).
 
  - Relocate the trip points handling code into a separate file (Daniel

  - Make the thermal core fail registration of thermal zones and cooling
    devices if the thermal class has not been registered (Rafael Wysocki).
 
  - Add trip point initialization helper functions for ACPI-defined trip
    points and modify two thermal drivers to use them (Rafael Wysocki,
    Daniel Lezcano).
 
  - Make the core thermal control code use sysfs_emit_at() instead of
    scnprintf() where applicable (ye xingchen).
 
  - Consolidate code accessing the Intel TCC (Thermal Control Circuitry)
    MSRs by introducing library functions for that and making the
    TCC-related code in thermal drivers use them (Zhang Rui).

Merge tag 'thermal-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control updates from Rafael Wysocki:
 "The majority of changes here are related to the general switch-over to
  using arrays of generic trip point structures registered along with a
  thermal zone instead of trip point callbacks (this has been done
  mostly by Daniel Lezcano with some help from yours truly on the Intel
  drivers front).

  Apart from that and the related reorganization of code, there are some
  enhancements of the existing driver and a new Mediatek Low Voltage
  Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
  rework so it will use the generic idle_inject facility for CPU idle
  time injection going forward and it will take additional module
  parameters for specifying the subset of CPUs to be affected by it
  (work done by Srinivas Pandruvada).

  Also included are assorted fixes and a whole bunch of cleanups.

  Specifics:

   - Rework a large bunch of drivers to use the generic thermal trip
     structure and use the opportunity to do more cleanups by removing
     unused functions from the OF code (Daniel Lezcano)

   - Remove core header inclusion from drivers (Daniel Lezcano)

   - Fix some locking issues related to the generic thermal trip rework
     (Johan Hovold)

   - Fix a crash when requesting the critical temperature on tegra,
     which is related to the generic trip point work (Jon Hunter)

   - Clean up thermal device unregistration code (Viresh Kumar)

   - Fix and clean up thermal control core initialization error code
     paths (Daniel Lezcano)

   - Relocate the trip points handling code into a separate file (Daniel
     Lezcano)

   - Make the thermal core fail registration of thermal zones and
     cooling devices if the thermal class has not been registered
     (Rafael Wysocki)

   - Add trip point initialization helper functions for ACPI-defined
     trip points and modify two thermal drivers to use them (Rafael
     Wysocki, Daniel Lezcano)

   - Make the core thermal control code use sysfs_emit_at() instead of
     scnprintf() where applicable (ye xingchen)

   - Consolidate code accessing the Intel TCC (Thermal Control
     Circuitry) MSRs by introducing library functions for that and
     making the TCC-related code in thermal drivers use them (Zhang Rui)

   - Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
     changes (Zhang Rui)

   - Address an "unsigned expression compared with zero" warning in the
     intel_soc_dts_iosf thermal driver (Yang Li)

   - Update comments regarding two functions in the Intel Menlow thermal
     driver (Deming Wang)

   - Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
     driver (ye xingchen)

   - Make the intel_pch thermal driver support the Wellsburg PCH (Tim
     Zimmermann)

   - Modify the intel_pch and processor_thermal_device_pci thermal
     drivers use generic trip point tables instead of thermal zone trip
     point callbacks (Daniel Lezcano)

   - Add production mode attribute sysfs attribute to the int340x
     thermal driver (Srinivas Pandruvada)

   - Rework dynamic trip point updates handling and locking in the
     int340x thermal driver (Rafael Wysocki)

   - Make the int340x thermal driver use a generic trip points table
     instead of thermal zone trip point callbacks (Rafael Wysocki,
     Daniel Lezcano)

   - Clean up and improve the int340x thermal driver (Rafael Wysocki)

   - Simplify and clean up the intel_pch thermal driver (Rafael Wysocki)

   - Fix the Intel powerclamp thermal driver and make it use the common
     idle injection framework (Srinivas Pandruvada)

   - Add two module parameters, cpumask and max_idle, to the Intel
     powerclamp thermal driver to allow it to affect only a specific
     subset of CPUs instead of all of them (Srinivas Pandruvada)

   - Make the Intel quark_dts thermal driver Use generic trip point
     objects instead of its own trip point representation (Daniel
     Lezcano)

   - Add toctree entry for thermal documents and fix two issues in the
     Intel powerclamp driver documentation (Bagas Sanjaya)

   - Use strscpy() to instead of strncpy() in the thermal core (Xu
     Panda)

   - Fix thermal_sampling_exit() (Vincent Guittot)

   - Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam
     Chihi)

   - Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert
     Uytterhoeven)

   - Fix useless call to set_trips() when resuming in the rcar_gen3
     thermal control driver and add interrupt support detection at init
     time to it (Niklas Söderlund)

   - Fix memory corruption in the hi3660 thermal driver (Yongqin Liu)

   - Fix include path for libnl3 in pkg-config file for libthermal
     (Vibhav Pant)

   - Remove syscfg-based driver for st as the platform is not supported
     any more (Alain Volmat)"

0d9bdd8a55 platform/x86: nvidia-wmi-ec-backlight: Add force module parameter
On some Lenovo Legion models, the backlight might be driven by either
one of nvidia_wmi_ec_backlight or amdgpu_bl0 at different times.

When the Nvidia WMI EC backlight interface reports the backlight is
controlled by the EC, the current backlight handling only registers
nvidia_wmi_ec_backlight (and registers no other backlight interfaces).

This hides (never registers) the amdgpu_bl0 interface, where as prior
to 6.1.4 users would have both nvidia_wmi_ec_backlight and amdgpu_bl0
and could work around things in userspace.

Add a force module parameter which can be used with acpi_backlight=native
to restore the old behavior as a workound (for now) by passing:

"acpi_backlight=native nvidia-wmi-ec-backlight.force=1"

Thanks to bugreport 216655 on bugzilla triggered by the
dell-smm-hwmon driver, the contents of the sensor buffers
could be almost completely decoded.
Add an hwmon interface for exposing the fan and thermal
sensor values. Since the WMI interface can be quite slow
on some machines, the sensor buffers are cached for 1 second
to lessen the performance impact.
The debugfs interface remains in place to aid in reverse-engineering
of unknown sensor types and the thermal buffer.

Currently hotplug configuration in logic device assumes that all items
are provided with no holes.
Thus, any group of hotplug events, associated with the specific
status/event/mask registers is configured in those registers
successively from bit zero to bit #n (#n < 8).

This logic is changed int order to allow non-successive definition to
support configuration with the skipped bits – for example bits 3, 5, 7
in status/event/mask registers can be associated with hotplug events,
while others can be skipped.

158cd83207 platform: mellanox: Split logic in init and exit flow
Split logic in mlxplat_init()/mlxplat_exit() routines.
Separate initialization of I2C infrastructure and others platform
drivers.

Motivation is to provide synchronization between I2C bus and mux
drivers and other drivers using this infrastructure.
I2C main bus and MUX busses are implemented in FPGA logic. On some new
systems the numbers allocated for these busses could be variable
depending on order of initialization of I2C native busses. Since bus
numbers are passed to some other platform drivers during initialization
flow, it is necessary to synchronize completion of I2C infrastructure
drivers and activation of rest of drivers.

Thus initialization flow will be performed in synchronized order.
