30 * DOC: overview
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.
