[RFC PATCH v3 6/9] ARM: dts: imx51: Add IPU ports and endpoints, move imx-drm node to dtsi (original) (raw)

This patch connects IPU and and parallel display device tree nodes using the OF graph bindings described in Documentation/devicetree/bindings/media/video-interfaces.txt

The IPU ports correspond to the two display interfaces. The order of endpoints in the ports is arbitrary.

Since the imx-drm node now only needs to contain links to the display interfaces, it can be moved to the SoC dtsi level. At the board level, only connections between the display interface ports and panels have to be added.
