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" * tag 'platform-drivers-x86-v6.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86: (112 commits) thermal/drivers/acerhdf: Constify struct thermal_zone_device_ops platform/x86/amd/hsmp: fix building with CONFIG_HWMON=m platform/x86: asus-wmi: fix build without CONFIG_SUSPEND docs: ABI: Fix "aassociated" to "associated" platform/x86: Add AMD ISP platform config for OV05C10 Documentation: admin-guide: pm: Add documentation for die_id platform/x86/intel-uncore-freq: Add attributes to show die_id platform/x86/intel: power-domains: Add interface to get Linux die ID Documentation: admin-guide: pm: Add documentation for agent_types platform/x86/intel-uncore-freq: Add attributes to show agent types platform/x86/tuxedo: Prevent invalid Kconfig state platform/x86: dell-ddv: Expose the battery health to userspace platform/x86: dell-ddv: Expose the battery manufacture date to userspace platform/x86: dell-ddv: Implement the battery matching algorithm power: supply: core: Add additional health status values platform/x86/amd/hsmp: acpi: Add sysfs files to display HSMP telemetry platform/x86/amd/hsmp: Report power via hwmon sensors platform/x86/amd/hsmp: Use a single DRIVER_VERSION for all hsmp modules platform/mellanox: mlxreg-dpu: Fix smatch warnings platform: mellanox: nvsw-sn2200: Fix .items in nvsw_sn2201_busbar_hotplug ...
2025-04-30power: supply: add inhibit-charge-awake to charge_behaviourAntheas Kapenekakis
OneXPlayer devices have a charge inhibit feature that allows the user to select between it being active always or only when the device is on. Therefore, add attribute inhibit-charge-awake to charge_behaviour to allow the user to select that charge should be paused only when the device is awake.

2025-04-29power: supply: support charge_types in extensionsJelle van der Waa
Similar to charge_behaviour, charge_types is an enum option where reading the property shows the supported values, with the active value surrounded by brackets. To be able to use it with a power_supply extension a bitmask with the supported charge_Types values has to be added to power_supply_ext.

2024-12-14power: supply: core: add UAPI to discover currently used extensionsThomas Weißschuh
Userspace wants to now about the used power supply extensions, for example to handle a device extended by a certain extension differently or to discover information about the extending device. Add a sysfs directory to the power supply device. This directory contains links which are named after the used extension and point to the device implementing that extension.

CHARGE_COUNTER is really general in other power supply drivers and Android also has an interface to monitor CHARGE_COUNTER, so let's add it into test framework. Set default as -1000 is because the default status is POWER_SUPPLY_STATUS_DISCHARGING, which means the counter should be negative, and 1000 means not zero but small enough.
