platform/x86: bitland-mifs-wmi: add CONFIG_LEDS_CLASS dependency

platform/x86: bitland-mifs-wmi: Add new Bitland MIFS WMI driver

2026-03-24T13:03:09+00:00

Add a new driver for Bitland laptops that utilize the MIFS (MiInterface) WMI interface. The driver implements several features through the WMI interface: - Platform Profile: Supports "Quiet", "Balanced", "Performance", and "Full Speed" modes. The "Full Speed" mode is intelligently restricted based on the AC adapter type (requires DC power, not supported on USB-C charging) as required by the hardware. - Hwmon: Provides monitoring for CPU, GPU, and System fan speeds, as well as CPU temperature sensors. - Keyboard Backlight: Integrated with the LED class device for brightness control and provides sysfs attributes for keyboard modes (cyclic, fixed, etc.). - GPU Mode: Allows switching between Hybrid, Discrete, and UMA graphics modes via sysfs. - Hotkeys: Handles WMI events for system hotkeys (Calculator, Browser, App launch) using sparse keymaps and reports status changes for Airplane mode, Touchpad, and CapsLock. - Fan Boost: Provides a sysfs interface to force fans to maximum speed. The driver registers two WMI GUIDs: - B60BFB48-3E5B-49E4-A0E9-8CFFE1B3434B: Control methods - 46C93E13-EE9B-4262-8488-563BCA757FEF: Event notifications Reviewed-by: Armin Wolf Signed-off-by: Mingyou Chen Link: https://patch.msgid.link/20260323132218.444383-1-qby140326@gmail.com Reviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen

The current set of DMI board IDs from the fixes branch is required to reorder them in the for-next branch.

platform/x86: ayaneo-ec: Move Ayaneo devices from oxpec to ayaneo-ec

2025-11-21T15:36:20+00:00

Currently, the oxpec driver contains Ayaneo devices. Move them to the new ayaneo-ec driver, which is dedicated to them. As this driver supports charge inhibition for Ayaneo, add support for it for the AIR, AIR 1S, AB05-Medoncino, AIR Pro, and Kun, referenced from the out-of-tree ayaneo-platform driver. In addition, update the readmes of oxpec to reflect this change. Link: https://github.com/ShadowBlip/ayaneo-platform Tested-by: Derek J.

platform/x86: ayaneo-ec: Add charge control support

2025-11-21T15:36:17+00:00

Ayaneo devices support charge inhibition via the EC. This inhibition only works while the device is powered on, and resets between restarts. However, it is maintained across suspend/resume cycles. The EC does not support charge threshold control. Instead, userspace software on Windows manually toggles charge inhibition depending on battery level.

platform/x86: ayaneo-ec: Add Ayaneo Embedded Controller platform driver

2025-11-21T15:36:12+00:00

Recent Ayaneo devices feature an ACPI mapped Embedded Controller (EC) with standard addresses across models that provides access to fan speed, fan control, battery charge limits, and controller power controls. Introduce a new driver stub that will handle these driver features.

platform/x86: asus-wmi: deprecate bios features

With the existence of the asus-armoury module the attributes no longer need to live under the /sys/devices/platform/asus-nb-wmi/ path. Deprecate all those that were implemented in asus-bioscfg with the goal of removing them fully in the next LTS cycle. Signed-off-by: Denis Benato Signed-off-by: Luke D.

platform/x86: asus-armoury: move existing tunings to asus-armoury module

2025-11-12T12:21:08+00:00

The fw_attributes_class provides a much cleaner interface to all of the attributes introduced to asus-wmi. This patch moves all of these extra attributes over to fw_attributes_class, and shifts the bulk of these definitions to a new kernel module to reduce the clutter of asus-wmi with the intention of deprecating the asus-wmi attributes in future. The work applies only to WMI methods which don't have a clearly defined place within the sysfs and as a result ended up lumped together in /sys/devices/platform/asus-nb-wmi/ with no standard API. Where possible the fw attrs now implement defaults, min, max, scalar, choices, etc. As en example dgpu_disable becomes: /sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/ ├── current_value ├── display_name ├── possible_values └── type as do other attributes.
