Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

arm-soc fixes for 3.3-rc:

AT91 needed reset fixes which resulted in some minor code refactoring,
it also adds a feature-removal for one of their platforms for 3.4.
The USB patches have been acked by Greg K-H.

i.MX and ux500 both have some minor fixes, nothing controversial.
