+description: |
+  Mediatek display dither processor, namely DITHER, works by approximating
+  unavailable colors with available colors and by mixing and matching available
+  colors to mimic unavailable ones.
+  DITHER device node must be siblings to the central MMSYS_CONFIG node.
+  For a description of the MMSYS_CONFIG binding, see
+  Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml
+  for details.
