In that case I'd like to take up the ball.

In my opinion the driver is now in a state in which it could be moved to
gpu/drm first and then fixed up there (all the blockers in
drivers/staging/imx-drm/TODO are gone). That would also give us a single
path for all imx-drm/ipu-v3 related patches again. My main motivation to
put it into staging in the first place was that the device tree bindings
had to be worked out, but now it only results in a coordination
nightmare.
