platform/x86/tuxedo: Add virtual LampArray for TUXEDO NB04 devices 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 <wse@tuxedocomputers.com> Link: https://lore.kernel.org/r/20250425210043.342288-2-wse@tuxedocomputers.com Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>

help
This driver implements the WMI AB device found on TUXEDO notebooks
with board vendor NB04. This enables keyboard backlight control via a
virtual HID LampArray device.
When compiled as a module it will be called tuxedo_nb04_wmi_ab.
