31 | * |
32 | * Display Controller Hub (DCHUB) is the gateway between the Scalable Data Port |
33 | * (SDP) and DCN. This component has multiple features, such as memory |
34 | * arbitration, rotation, and cursor manipulation. |
35 | * |
36 | * There is one HUBP allocated per pipe, which fetches data and converts |
37 | * different pixel formats (i.e. ARGB8888, NV12, etc) into linear, interleaved |
38 | * and fixed-depth streams of pixel data. |
