I am happy with the series so far. Pending Acks from the device tree
maintainers for the new binding documents, I'd like to apply either the
whole of it on top of
    git://git.pengutronix.de/git/pza/linux.git imx-drm/next
or take at least the i.MX specific patches (1-5) because of the
dependency on the imx-drm OF helper conversion.

regards
Philipp
