Well, the problem is that your branch generates conflicts with the 
at91/cleanup one that Olof have just pulled. They are not big conflicts, 
only additions of header files at the same location.
Maybe you can rebase your branch on top of this cleanup branch 
(arm-soc/next/cleanup: 94c5216ee93b3b4).

But, anyway I feel that it is better if you take the whole series in a raw.
