Merge the fixes branch into the for-next branch to resolve Makefile conflict and include the power supply accessor work that is required by the upcoming Uniwill driver.

platform/x86: Fix initialization order for firmware_attributes_class

2025-07-11T15:52:54+00:00

The think-lmi driver uses the firwmare_attributes_class. But this class is registered after think-lmi, causing the "think-lmi" directory in "/sys/class/firmware-attributes" to be missing when the driver is compiled as builtin.

platform/x86: portwell-ec: Add GPIO and WDT driver for Portwell EC

2025-05-08T14:37:58+00:00

Adds a driver for the ITE Embedded Controller (EC) on Portwell boards. It integrates with the Linux GPIO and watchdog subsystems to provide: - Control/monitoring of up to 8 EC GPIO pins. - Hardware watchdog timer with 1-255 second timeouts. The driver communicates with the EC via I/O port 0xe300 and identifies the hardware by the "PWG" firmware signature. This enables enhanced system management for Portwell embedded/industrial platforms.

platform/x86/tuxedo: Add virtual LampArray for TUXEDO NB04 devices

2025-05-08T13:03:58+00:00

The TUXEDO Sirius 16 Gen1 and TUXEDO Sirius 16 Gen2 devices have a per-key controllable RGB keyboard backlight. The firmware API for it is implemented via WMI. To make the backlight userspace configurable this driver emulates a LampArray HID device and translates the input from hidraw to the corresponding WMI calls. This is a new approach as the leds subsystem lacks a suitable UAPI for per-key keyboard backlights, and like this no new UAPI needs to be established. The handle_* functions an corresponding structs are named based on the HID spec: HID Usage Tables 1.6 -> 26 Lighting And Illumination Page (0x59) Signed-off-by: Werner Sembach Link: https://lore.kernel.org/r/20250425210043.342288-2-wse@tuxedocomputers.com Reviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen

platform/x86: Introduce dasharo-acpi platform driver

2025-05-08T13:03:18+00:00

Introduce a driver for devices running Dasharo firmware. The driver supports thermal monitoring using a new ACPI interface in Dasharo. The initial version supports monitoring fan speeds, fan PWM duty cycles and system temperatures as well as determining which specific interfaces are implemented by firmware. It has been tested on a NovaCustom laptop running pre-release Dasharo firmware, which implements fan and thermal monitoring for the CPU and the discrete GPU, if present.

platform/x86: oxpec: Move hwmon/oxp-sensors to platform/x86

2025-04-30T11:04:56+00:00

The EC of OneXPlayer devices used to only control the fan. This is no longer the case, with the EC of OneXPlayer gaining additional functionality (turbo button, turbo led, battery controls). As it will be beneficial from a complexity perspective to retain this driver as a single unit, move it out of hwmon, and into platform/x86. Also, remove the hwmon documentation to prepare moving it to Documentation/ABI/. While at it, add myself to the maintainer's file.
