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

Pull arm-soc bug fixes from Olof Johansson:

 - A set of OMAP fixes, about half of them PM/clock related, the rest
   scattered over the platform code but all small and targeted to real
   bugs.
 - Two small i.MX fixes for SSI device clock setup.
