New and updated SoC support, notable changes include:
* bcm: brcmstb SMP support
* bcm: initial iproc/cygnus support
* exynos: Exynos4415 SoC support
* exynos: PMU and suspend support for Exynos5420
* exynos: PMU support for Exynos3250
* exynos: pm related maintenance
* imx: new LS1021A SoC support
* imx: vybrid 610 global timer support
* integrator: convert to using multiplatform configuration
* mediatek: earlyprintk support for mt8127/mt8135
* meson: meson8 soc and l2 cache controller support
* mvebu: Armada 38x CPU hotplug support
* mvebu: drop support for prerelease Armada 375 Z1 stepping
* mvebu: extended suspend support, now works on Armada 370/XP
* omap: hwmod related maintenance
* omap: prcm cleanup
* pxa: initial pxa27x DT handling
* rockchip: SMP support for rk3288
* rockchip: add cpu frequency scaling support
* shmobile: r8a7740 power domain support
* shmobile: various small restart, timer, pci apmu changes
* sunxi: Allwinner A80 (sun9i) earlyprintk support
* ux500: power domain support
Overall, a significant chunk of changes, coming mostly from
the usual suspects: omap, shmobile, samsung and mvebu, all of
which already contain a lot of platform specific code in
arch/arm.
