This connects the IPU and display encoder (HDMI, LVDS, MIPI) device tree nodes using the bindings described in Documentation/devicetree/bindings/media/video-interfaces.txt The IPU ports correspond to the two display interfaces. Port numbering begins at 2 to leave space for the two CSI input ports. The order of endpoints in the ports is arbitrary. Each encoder with an associated input multiplexer has multiple input ports in the device tree. The order and reg property of the ports must correspond to the multiplexer input order.
