29 Scaler  section in Overview of D71 like display IPs
31 As its name suggests, scaler takes responsibility for scaling, and D71 also
32 supports image enhancements by scaler.
33 The usage of scaler is very flexible and can be connected to layer output
43 user can also insert a scaler between compositor and wb_layer to down scale
63 D71 scaler mostly only has the half horizontal input/output capabilities
64 compared with Layer, like if Layer supports 4K input size, the scaler only can
