description: |
  Khadas embeds a microcontroller on their VIM and Edge boards adding some
  system feature as PWM Fan control (for VIM2 rev14 or VIM3), User memory
  storage, IR/Key resume control, system power LED control and more.

properties:
  compatible:
    enum:
      - khadas,mcu # MCU revision is discoverable

  "#cooling-cells": # Only needed for boards having FAN control feature
    const: 2

  reg:
    maxItems: 1

required:
  - compatible
  - reg
