Pull ARM SoC platform changes from Arnd Bergmann:
 "New and updated SoC support, notable changes include:

   - bcm:
        brcmstb SMP support
        initial iproc/cygnus support
   - exynos:
        Exynos4415 SoC support
        PMU and suspend support for Exynos5420
        PMU support for Exynos3250
        pm related maintenance
   - imx:
        new LS1021A SoC support
        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
        drop support for prerelease Armada 375 Z1 stepping
        extended suspend support, now works on Armada 370/XP
   - omap:
        hwmod related maintenance
        prcm cleanup
   - pxa:
        initial pxa27x DT handling
   - rockchip:
        SMP support for rk3288
        add cpu frequency scaling support
   - shmobile:
        r8a7740 power domain support
        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"
