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. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> --- Changes since v4: - 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/imx51-apf51dev.dts | 11 ++++++++++- arch/arm/boot/dts/imx51-babbage.dts | 28 ++++++++++++++++++++-------- arch/arm/boot/dts/imx51.dtsi | 22 +++++++++++++++++++++- 3 files changed, 51 insertions(+), 10 deletions(-)
