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

Pull ARM SoC platform updates from Arnd Bergmann:
 "SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
  for a few platforms:

   - Andres Färber adds initial support for the Actions Semi S500 (aka
     'owl') platform, a close relative of the S900 platform he adds for
     arm64.

   - in mach-omap2, we remove more legacy code

   - Rockchips gains support for the RV1108 SoC designed for camera
     applications.

   - For Atmel, we gain support for MMU-less SoCs (SAME70/V71/S70/V70)

   - Minor updates for other platforms, including davinci, s3c64xx,
     prima2, stm32, broadcom nsp, amlogic, pxa, imx and renesas"
