14  Mediatek display split, namely SPLIT, is used to split stream to two
15  encoders.
16  SPLIT 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.
