From: Kieran Bingham <kieran.bingham@ideasonboard.com> Provide a device node for the ADV7511 as found on the Draak D3 platform. The ADV7511 is connected to the DU through a parallel mux chip, and is configurable in hardware whether it is connected to LVDS0 or LVDS1. Connect through to LVDS0 as a default implementation.
