description: |
  Mediatek display dither processor, namely DITHER, works by approximating
  unavailable colors with available colors and by mixing and matching available
  colors to mimic unavailable ones.
  DITHER device node must be siblings to the central MMSYS_CONFIG node.
  For a description of the MMSYS_CONFIG binding, see
  Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml
  for details.
