Linus Torvalds bab588fcfb arm-soc: soc-specific updates 
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 * socfpga now supports a newer version of the hardware including SMP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
