Yep, I've rebased and applied it to the ux500-devicetree
branch.

I have some stuff on this branch which is queued up but may
miss v3.11, because I need the 5 outstanding pull requests
to land in ARM SoC so I get a merge base there before I
can send any more stuff.

It's mainly because this stuff isn't any orthogonal, everything
just conflicts in the AUXDATA all the time.

Yours,
Linus Walleij
