  14   Mediatek display postmask, namely POSTMASK, provides round corner pattern
  15   generation.
  16   POSTMASK 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
