description: |

|
|
Mediatek display UFOe stands for Unified Frame Optimization engine.
|
||
|
|
UFOe can cut the data rate for DSI port which may lead to reduce power
|
||
|
|
consumption.
|
||
|
|
UFOe 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.
