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.
