Both parallel and Bt.656 are supported. So you'll need the bus-type
property. Looking further the datasheet, you'll also need pclk-sample,
hsync-active and vsync-active properties. I'd make them mandatory for the
endpoint (the two latter are for parallel mode only).

Please also add the above properties here.
