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

Pull ARM SoC-specific updates from Arnd Bergmann:
 "This is a larger set of new functionality for the existing SoC
  families, including:

   - vt8500 gains support for new CPU cores, notably the Cortex-A9 based
     wm8850

   - prima2 gains support for the "marco" SoC family, its SMP based
     cousin

   - tegra gains support for the new Tegra4 (Tegra114) family

   - socfpga now supports a newer version of the hardware including SMP

   - i.mx31 and bcm2835 are now using DT probing for their clocks

   - lots of updates for sh-mobile

   - OMAP updates for clocks, power management and USB

   - i.mx6q and tegra now support cpuidle

   - kirkwood now supports PCIe hot plugging

   - tegra clock support is updated

   - tegra USB PHY probing gets implemented diffently"
