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:
 "Improved and new platform support for various SoCs:

  New SoC support:
   - Broadcom BCM23550
   - Freescale i.MX7Solo
   - Qualcomm MDM9615
   - Renesas r8a7792

  Improvements:
   - convert clps711x to multiplatform
   - debug uart improvements for Atmel platforms
   - Tango platform improvements: HOTPLUG_CPU, Suspend-to-ram
   - OMAP tweaks and improvements to hwmod
   - OMAP support for kexec on SMP"
