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