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* socfpga now supports a newer version of the hardware including SMP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