Hi,
here is an updated and more complete version of the imx-drm DT binding series. These patches apply on top of Russell's second preview of the imx-drm cleanup series on v3.14-rc2. I have added device tree bindings between IPU and the encoders as documented in Documentation/devicetree/bindings/media/video-interfaces.txt and used those to determine the possible_crtcs and mux_id.
The crtc cookie is replaced with a the port device tree node, which is unique and therefore allows to get rid of the di_id comparison. Storing the multiplexer input numbers in the device tree removes the need to know the ipu_id. This should also allow to replace IPU2 with LCDIF on i.MX6 Solo more easily.
In v3 also connections between display interface ports and encoders are used to find all necessary components, so that only the display interfaces have to be configured in the imx-drm node. This allows to move the imx-drm node into the SoC level dtsi. I've also updated the existing i.MX51 and i.MX53 device trees this time and updated/added the devicetree binding documentation.
Patch 2/9 adds a temporary copy of the v4l2_of parser functions. Those are going to be moved to some place where they can be used by drm drivers, eventually, so those local copies can be dropped again.
Russell has sent a pull request for the imx-drm component support series now, and we're at v3.13-rc4 already. This patch series still applies on top of git://ftp.arm.linux.org.uk/~rmk/linux-arm.git imx-drm-staging I'd appreciate some feedback on this. Or shall I resend without the RFC?
regards Philipp
