14 Mediatek display color correction, namely CCORR, reproduces correct color
15 on panels with different color gamut.
16 CCORR 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.
