Merge tag 'platform-drivers-x86-v6.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86

Pull x86 platform driver updates from Ilpo Järvinen:

 - acer-wmi: Add PH16-72, PHN16-72, and PT14-51 fan control support

 - acpi: platform_profile: Add max-power profile option (power draw
   limited by the cooling hardware, may exceed battery power draw limit
   when on AC power)

 - amd/hsmp: Allow more than one data-fabric per socket

 - asus-armoury: Add WMI attributes driver to expose miscellaneous WMI
   functions through fw_attributes (deprecates the custom BIOS features
   interface through asus-wmi)

 - asus-wmi: Use brightness_set_blocking() for kbd led

 - ayaneo-ec: Add Ayaneo Embedded Controller driver

 - fs/nls:
     - Fix utf16 to utf8 string conversion when output size restricted
     - Improve error code consistency for utf8 to utf32 conversions

 - ideapad-laptop: Fast (Rapid Charge) charge type support

 - intel/hid: Add Dell Pro Rugged 10/12 tablet to VGBS DMI quirks

 - intel/pmc:
     - Arrow Lake telemetry GUID improvements
     - Add support for Wildcat Lake PMC information

 - intel_pmc_ipc: Fix ACPI buffer memleak

 - intel/punit_ipc: Fix memory corruption

 - intel/vsec: Wildcat Lake PMT telemetry support

 - lenovo-wmi-gamezone: Map "Extreme" performance mode to max-power

 - lg-laptop: Add support for the HDAP opregion field

 - serial-multi-instantiate: Add IRQ_RESOURCE_OPT for IRQ missing
   projects

 - thinkpad-t14s-ec: Improve suspend/resume support (lid LEDs, keyboard
   backlight)

 - uniwill: Add Uniwill laptop driver

 - wmi: Move under drivers/platform/wmi as non-x86 WMI support is around
   the corner and other WMI features will require adding more C files as
   well

 - tools/power/x86/intel-speed-select: v1.24
     - Check feature status to check if the feature enablement was
       successful
     - Reset SST-TF bucket structure to display valid bucket info

 - Miscellaneous cleanups / refactoring / improvements

+Uniwill laptop extra features
+=============================
+
+On laptops manufactured by Uniwill (either directly or as ODM), the ``uniwill-laptop`` driver
+handles various platform-specific features.
+
+Module Loading
+--------------
+
+The ``uniwill-laptop`` driver relies on a DMI table to automatically load on supported devices.
+When using the ``force`` module parameter, this DMI check will be omitted, allowing the driver
+to be loaded on unsupported devices for testing purposes.
+
+Hotkeys
+-------
+
+Usually the FN keys work without a special driver. However as soon as the ``uniwill-laptop`` driver
+is loaded, the FN keys need to be handled manually. This is done automatically by the driver itself.
+
+Keyboard settings
+-----------------
+
+The ``uniwill-laptop`` driver allows the user to enable/disable:
+
+ - the FN and super key lock functionality of the integrated keyboard
+ - the touchpad toggle functionality of the integrated touchpad
+
+See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details.
+
+Hwmon interface
+---------------
+
+The ``uniwill-laptop`` driver supports reading of the CPU and GPU temperature and supports up to
+two fans. Userspace applications can access sensor readings over the hwmon sysfs interface.
+
+Platform profile
+----------------
+
+Support for changing the platform performance mode is currently not implemented.
+
+Battery Charging Control
+------------------------
+
+The ``uniwill-laptop`` driver supports controlling the battery charge limit. This happens over
+the standard ``charge_control_end_threshold`` power supply sysfs attribute. All values
+between 1 and 100 percent are supported.
+
+Additionally the driver signals the presence of battery charging issues through the standard
+``health`` power supply sysfs attribute.
+
+Lightbar
+--------
+
+The ``uniwill-laptop`` driver exposes the lightbar found on some models as a standard multicolor
+LED class device. The default name of this LED class device is ``uniwill:multicolor:status``.
+
+See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details on how to control the various
+animation modes of the lightbar.
