Merge tag 'soc-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next

Pull part one of ARM SoC updates from Olof Johansson:
 "A quite large set of SoC updates this cycle.  In no particular order:

   - Multi-cluster power management for Samsung Exynos, adding support
     for big.LITTLE CPU switching on EXYNOS5

   - SMP support for Marvell Armada 375 and 38x

   - SMP rework on Allwinner A31

   - Xilinx Zynq support for SOC_BUS, big endian

   - Marvell orion5x platform cleanup, modernizing the implementation
     and moving to DT.

   - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
     that their platform can be enabled in the same kernel binary as
     most of the other v7 platforms in the tree.  \o/

     The work isn't quite complete, there's some driver fixes still
     needed, but the basics now work.

  New SoC support added:

   - Freescale i.MX6SX

   - LSI Axxia AXM55xx SoCs

   - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800

   - STi STIH407

  plus a large set of various smaller updates for different platforms.
  I'm probably missing some important one here"
