Hi,
this latest version of the imx-drm DT binding patches applies on top of staging-next and also depends on the OF graph binding patchset that moves the v4l2_of helpers to drivers/of. Currently, the two patchsets are also available at: git://git.pengutronix.de/git/pza/linux.git topic/of-graph git://git.pengutronix.de/git/pza/linux.git topic/imx-drm-dt
I have added device tree bindings between IPU and the encoders as documented in Documentation/devicetree/bindings/graph.txt and used those to determine the possible_crtcs and mux_id, and to find all necessary components that hang off of the display interface ports. This allows to move the imx-drm node into the SoC level dtsi. The existing i.MX51 and i.MX53 device trees are updated and device tree binding documentation is included.
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' - Fixed copy&paste documentation error and added optional 'ddc-i2c-bus' property in HDMI binding documentation - Fixed imx-tve and imx-hdmi to use the common 'ddc-i2c-bus' property as already used by the simple-panel binding instead of the custom but very generic 'ddc'.
regards Philipp
