From: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>
The Draak board has an ADV7180 CVBS decoder and an ADV7612 HDMI decoder,
both connected to the same VIN input. DIP switches are used to select
one of the two devices, with the HDMI decoder being the default. Add an
overlay that selects the CVBS decoder.
