description: |
  MediaTek color processor, namely COLOR, provides hue, luma and saturation
  adjustments to get better picture quality and to have one panel
  resemble the other in their output characteristics.
  COLOR 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.
