Merge branch 'imx-drm-staging' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into staging-next 

Russell writes:

These changes, which convert imx-drm to use the recently merged
component infrastructure, have been reviewed and acked by Philipp Zabel,
Shawn Guo and Fabio Estevam, and are now deemed to be ready.
