[RFC PATCH v2 0/4] imx-drm dt bindings

Hi,

these patches apply on top of Russell's second preview of the
imx-drm cleanup series. 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 v2 I've added temporary copies of the v4l2_of helpers to imx-drm
and tested it on the SolidRun Hummingboard.

regards
Philipp
