[RFC PATCH 1/3] ARM: dts: imx6qdl: Add ports and endpoints to IPU DIs
Philipp Zabel

Mon Jan 6 09:52:00 EST 2014
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.
