Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform updates from Olof Johansson:
 "Our SoC branch usually contains expanded support for new SoCs and
  other core platform code.  In this case, that includes:

   - support for the new Annapurna Labs "Alpine" platform

   - a rework greatly simplifying adding new platform support to the
     MCPM subsystem (Multi-cluster power management)

   - cpuidle and PM improvements for Exynos3250

   - misc updates for Renesas, OMAP, Meson, i.MX.  Some of these could
     have gone in other branches but ended up here for various reasons"
