Merge tag 'platform-drivers-x86-v6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86

Pull x86 platform driver updates from Ilpo Järvinen:

 - New acer-wmi HW support

 - Support for new revision of amd/pmf heartbeat notify

 - Correctly handle asus-wmi HW without LEDs

 - fujitsu-laptop battery charge control support

 - Support for new hp-wmi thermal profiles

 - Support ideapad-laptop refresh rate key

 - Put intel/pmc AI accelerator (GNA) into D3 if it has no driver to
   allow entry into low-power modes, and temporarily removed Lunar Lake
   SSRAM support due to breaking FW changes causing probe fail (further
   breaking FW changes are still pending)

 - Report pmc/punit_atom devices that prevent reacing low power levels

 - Surface Fan speed function support

 - Support for more sperial keys and complete the list of models with
   non-standard fan registers in thinkpad_acpi

 - New DMI touchscreen HW support

 - Continued modernization efforts of wmi

 - Removal of obsoleted ledtrig-audio call and the related dependency

 - Debug & metrics interface improvements

 - Miscellaneous cleanups / fixes / improvements
