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:
 "New or improved SoC support:

   - add support for Atmel's SAMA5D2 SoC
   - add support for Freescale i.MX6UL
   - improved support for TI's DM814x platform
   - misc fixes and improvements for RockChip platforms
   - Marvell MVEBU suspend/resume support

  A few driver changes that ideally would belong in the drivers branch
  are also here (acked by appropriate maintainers):

   - power key input driver for Freescale platforms (svns)
   - RTC driver updates for Freescale platforms (svns/mxc)
   - clk fixes for TI DM814/816X

  + a bunch of other changes for various platforms"
