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:
 "Most of the commits are for defconfig changes, to enable newly added
  drivers or features that people have started using. For the changed
  lines lines, we have mostly cleanups, the affected platforms are OMAP,
  Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.

  The largest single change is the introduction of the TI "sysc" bus
  driver, with the intention of cleaning up more legacy code.

  Two new SoC platforms get added this time:

   - Allwinner R40 is a modernized version of the A20 chip, now with a
     Quad-Core ARM Cortex-A7. According to the manufacturer, it is
     intended for "Smart Hardware"

   - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family of
     chips meant for managed gigabit ethernet switches, based around a
     Cortex-A9 CPU.

  Finally, we gain SMP support for two platforms: Renesas R-Car E2 and
  Amlogic Meson8/8b, which were previously added but only supported
  uniprocessor operation"
