Merge tag 'platform-drivers-x86-v6.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86

Pull x86 platform drivers updates from Ilpo Järvinen:
 "The changes are mostly business as usual. Besides pdx86 changes, there
  are a few power supply changes needed for related pdx86 features, move
  of oxpec driver from hwmon (oxp-sensors) to pdx86, and one FW version
  warning to hid-asus.

  Highlights:

   - alienware-wmi-wmax:
       - Add HWMON support
       - Add ABI and admin-guide documentation
       - Expose GPIO debug methods through debug FS
       - Support manual fan control and "custom" thermal profile

   - amd/hsmp:
       - Add sysfs files to show HSMP telemetry
       - Report power readings and limits via hwmon

   - amd/isp4: Add AMD ISP platform config for OV05C10

   - asus-wmi:
       - Refactor Ally suspend/resume to work better with older FW
       - hid-asus: check ROG Ally MCU version and warn about old FW versions

   - dasharo-acpi:
       - Add driver for Dasharo devices supporting fans and temperatures
         monitoring

   - dell-ddv:
       - Expose the battery health and manufacture date to userspace
         using power supply extensions
       - Implement the battery matching algorithm

   - dell-pc:
       - Improve error propagation
       - Use faux device

   - int3472:
       - Add delays to avoid GPIO regulator spikes
       - Add handshake pin support
       - Make regulator supply name configurable and allow registering
         more than 1 GPIO regulator
       - Map mt9m114 powerdown pin to powerenable

   - intel/pmc: Add separate SSRAM Telemetry driver

   - intel-uncore-freq: Add attributes to show agent types and die ID

   - ISST:
       - Support SST-TF revision 2 (allows more cores per bucket)
       - Support SST-PP revision 2 (fabric 1 frequencies)
       - Remove unnecessary SST MSRs restore (the package retains MSRs
         despite CPU offlining)

   - mellanox: Add support for SN2201, SN4280, SN5610, and SN5640

   - mellanox: mlxbf-pmc: Support additional PMC blocks

   - oxpec:
       - Add OneXFly variants
       - Add support for charge limit, charge thresholds, and turbo LED
       - Distinguish current X1 variants to avoid unwanted matching to
         new variants
       - Follow hwmon conventions
       - Move from hwmon/oxp-sensors to platform/x86 to match the
         enlarged scope

   - power supply:
       - Add inhibit-charge-awake (needed by oxpec)
       - Add additional battery health status values ("blown fuse" and
         "cell imbalance") (needed by dell-ddv)

   - powerwell-ec: Add driver for Portwell EC supporting GPIO and watchdog

   - thinkpad-acpi: Support camera shutter switch hotkey

   - tuxedo: Add virtual LampArray for TUXEDO NB04 devices

   - tools/power/x86/intel-speed-select:
       - Support displaying SST-PP revision 2 fields
       - Skip uncore frequency update on newer generations of CPUs

   - Miscellaneous cleanups / refactoring / improvements"
