  13 description: |
  14   Mediatek display overdrive, namely OD, increases the transition values
  15   of pixels between consecutive frames to make LCD rotate faster.
  16   OD device node must be siblings to the central MMSYS_CONFIG node.
  17   For a description of the MMSYS_CONFIG binding, see
  18   Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml
  19   for details.
