I started writing a proper driver for the Khadas MCU present on the VIM2 rev 13, VIM3, VIM3L and Edge boards :
The main feature is to have FAN control, this adds it as hwmon device and cooling-devices added the the cpu thermal zone as active cooling devices in addition to the CPUs DVFS in passive & hot.
It also adds a power-off driver, and an nvmem driver for the USER memory.
I plan to send it to the upstream mailing-lists this week, but I’d like to have some tests and feedbacks !
I haven’t added it to the VIM2 DT since I don’t know how to handle the second revision of the board upstream, but it should work just fine.
