[GIT PULL] platform-drivers-x86 for v6.18-1
From: Ilpo Järvinen
Date: Tue Sep 30 2025 - 07:25:17 EST
Hi Linus,
Here is the main PDx86 PR for v6.18.
There's one-liner change into sound/ due to x86-android-tables moving away
from using GPIO legacy APIs which changes the name of a SPI/codec device.
Highlights
- amd/pmf:
- Add support for adjusting PMF PPT and PPT APU thresholds
- Extend custom BIOS inputs for more policies
- Update ta_pmf_action structure to the latest PMF TA
- arm64: thinkpad-t14s-ec: Add EC driver for ThinkPad T14s Gen6 Snapdragon
- int3472: Increase handshake GPIO delay
- intel/pmc:
- SSRAM support for Lunar Lake and Panther Lake
- Support reading substate requirements data from S0ix blockers
(for platforms starting from Panther Lake)
- Wildcat Lake support
- intel-uncore-freq:
- Solve duplicate sysfs entry warnings
- Present unique domain ID per package
- portwell-ec:
- Support suspend/resume
- Add hwmon support for voltage and temperature
- redmi-wmi: Add WMI driver for Redmibook keyboard
- think-lmi Certificate support for ThinkCenter
- x86-android-tables + others: Convert away from legacy GPIO APIs
- x86-android-tables:
- Add support for Acer A1-840 tablet
- Fix modules list for Lenovo devices
- Stop using EPROBE_DEFER
- Miscellaneous cleanups / refactoring / improvements
Regards, i.
