Pull x86 platform driver updates from Ilpo Järvinen:
 "acer-wmi:
   - Add support for PH14-51, PH16-72, and Nitro AN515-58
   - Add proper hwmon support
   - Improve error handling when reading "gaming system info"
   - Replace direct EC reads for the current platform profile with WMI
     calls to handle EC address variations
   - Replace custom platform_profile cycling with the generic one

  ACPI:
   - platform_profile: Major refactoring and improvements
   - Support registering multiple platform_profile handlers concurrently
     to avoid the need to quirk which handler takes precedence
   - Support reporting "custom" profile for cases where the current
     profile is ambiguous or when settings tweaks are done outside the
     pre-defined profile
   - Abstract and layer platform_profile API better using the class_dev
     and drvdata
   - Various minor improvements
   - Add Documentation and kerneldoc

  amd/hsmp:
   - Add support for HSMP protocol v7

  amd/pmc:
   - Support AMD 1Ah family 70h
   - Support STB with Ryzen desktop SoCs

  amd/pmf:
   - Support Custom BIOS inputs for PMF TA
   - Support passing SRA sensor data from AMD SFH (HID) to PMF TA

  dell-smo8800:
   - Move SMO88xx quirk away from the generic i2c-i801 driver
   - Add accelerometer support for Dell Latitude E6330/E6430 and XPS
     9550
   - Support probing accelerometer for models yet to be listed in the
     DMI mapping table because ACPI lacks i2c-address for the
     accelerometer (behind a module parameter because probing might be
     dangerous)

  HID:
   - amd_sfh: Add support for exporting SRA sensor data

  hp-wmi:
   - Add fan and thermal support for Victus 16-s1000

  input:
   - Add key for phone linking
   - i8042: Add context for the i8042 filter to enable cleaning up the
     filter related global variables from pdx86 drivers

  lenovo-wmi-camera:
   - Use SW_CAMERA_LENS_COVER instead of KEY_CAMERA_ACCESS

  mellanox mlxbf-pmc:
   - Add support for monitoring cycle count
   - Add Documentation

  thinkpad_acpi:
   - Add support for phone link key

  tools/power/x86/intel-speed-select:
   - Fix Turbo Ratio Limit restore

  x86-android-tables:
   - Add support for Vexia EDU ATLA 10 Bluetooth and EC battery driver

  And miscellaneous cleanups / refactoring / improvements"

+
+		This file can be monitored for changes by polling for POLLPRI,

+Description:
+		Start or stop counters. This is used to start the counters
+		for monitoring the programmed events and also to stop the
+		counters after the desired duration. Writing value 1 will
+		start all the counters in the block, and writing 0 will

+Description:
+		Value of register. This is used to read or reset the registers
+		where various performance statistics are counted for each block.
+		Writing 0 to the sysfs will clear the counter, writing any other

+Description:
+		Use a counter for counting cycles. This is used to repurpose/dedicate
+		any of the counters in the block to counting cycles. Each counter is
+		represented by a bit (bit 0 for counter0, bit1 for counter1 and so on)
+		and setting the corresponding bit will reserve that specific counter
