+ * 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.
