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