0014 Mediatek display overdrive, namely OD, increases the transition values
0015 of pixels between consecutive frames to make LCD rotate faster.
0016 OD device node must be siblings to the central MMSYS_CONFIG node.
0017 For a description of the MMSYS_CONFIG binding, see
0018 Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml
0019 for details.
