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- socfpga now supports a newer version of the hardware including SMP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