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.
