Hi Ulf,

I looked at all the changes, and they seem reasonable to me. Please
add my

Acked-by: Arnd Bergmann <arnd at arndb.de>

and put them into a separate branch that you merge into your mmc
git, so we can merge the changes with the other updates in case
there are conflicts.

I see that the only code change is in patch 2. Are you able to put
that patch last in the series without introducing bisection problems?
That would be preferred, as it allows us to keep a pure 'DT' branch
if we end up merging your other seven patches in.
