Verisilicon has a series of display controllers prefixed with DC and with self-identification facility like their GC series GPUs. Add a device tree binding for it. Depends on the specific DC model, it can have either one or two display outputs, and each display output could be set to DPI signal or "DP" signal (which seems to be some plain parallel bus to HDMI controllers).
