/**
* DOC: overview
*
* The DPP (Display Pipe and Plane) block is the unified display data
* processing engine in DCN for processing graphic or video data on per DPP
* rectangle base. This rectangle can be a part of SLS (Single Large Surface),
* or a layer to be blended with other DPP, or a rectangle associated with a
* display tile.
*
* It provides various functions including:
* - graphic color keyer
* - graphic cursor compositing
* - graphic or video image source to destination scaling
* - image sharping
* - video format conversion from 4:2:0 or 4:2:2 to 4:4:4
* - Color Space Conversion
* - Host LUT gamma adjustment
* - Color Gamut Remap
* - brightness and contrast adjustment.
*
* DPP pipe consists of Converter and Cursor (CNVC), Scaler (DSCL), Color
* Management (CM), Output Buffer (OBUF) and Digital Bypass (DPB) module
* connected in a video/graphics pipeline.
