It's a shame we didn't manage to pull these in in time for 4.1,
but while the patches look ok to me, they came a little late,
and it's not clear to me how we should maintain that platform.

You have lots of people on 'To:' for the emails, which is always
confusing. My preferred way of merging these in 4.2 would be for
you to send the patches to the imx maintainers so they can
pick them up and send them to arm@...nel.org.
