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

Pull ARM SoC fixes from Olof Johansson:
 "A smallish batch of fixes, a little more than expected this late, but
  all fixes are contained to their platforms and seem reasonably low
  risk:

   - a somewhat large SMP fix for ux500 that still seemed warranted to
     include here
   - OMAP DT fixes for pbias regulator specification that broke due to
     some DT reshuffling
   - PCIe IRQ routing bugfix for i.MX
   - networking fixes for keystone
   - runtime PM for OMAP GPMC
   - a couple of error path bug fixes for exynos"
