[RFC PATCH v4 7/8] ARM: dts: imx6qdl: Add IPU DI ports and endpoints, move imx-drm node to dtsi
Philipp Zabel

Tue Feb 25 09:23:22 EST 2014
This patch connects IPU and display encoder (HDMI, LVDS, MIPI)
device tree nodes, as well as parallel displays on the DISP0
and DISP1 outputs, 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.
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.
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 encoders or panels have to be added.

Changes since v3:
- Removed port at 4 output nodes from lvds-channel nodes for now.
