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.
Signed-off-by: Philipp Zabel p.zabel@pengutronix.de --- - Changed DT compatible string to 'fsl,imx-display-subsystem' instead of Linux specific 'fsl,imx-drm', changed DT node name from 'imx-drm' to 'display-subsystem'. --- arch/arm/boot/dts/imx6dl.dtsi | 22 +++--- arch/arm/boot/dts/imx6q-sabresd.dts | 4 -- arch/arm/boot/dts/imx6q.dtsi | 124 ++++++++++++++++++++++++++++++-- arch/arm/boot/dts/imx6qdl-sabresd.dtsi | 6 -- arch/arm/boot/dts/imx6qdl.dtsi | 128 ++++++++++++++++++++++++++++++++- 5 files changed, 253 insertions(+), 31 deletions(-)
