31  * DOC: overview
32  *
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
37  * display tile.
38  *
39  * It provides various functions including:
40  * - graphic color keyer
41  * - graphic cursor compositing
42  * - graphic or video image source to destination scaling
43  * - image sharping
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
47  * - Color Gamut Remap
48  * - brightness and contrast adjustment.
49  *
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.
