   14   Mediatek display UFOe stands for Unified Frame Optimization engine.
   15   UFOe can cut the data rate for DSI port which may lead to reduce power
   16   consumption.
   17   UFOe device node must be siblings to the central MMSYS_CONFIG node.
   18   For a description of the MMSYS_CONFIG binding, see
   19   Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml
   20   for details.
