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.
