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:
 "These are updates for platform specific code on 32-bit ARM machines,
  essentially anything that can not (yet) be expressed using DT files.

  Noteworthy changes include:

   - We get support for running in big-endian mode on two platforms:
     sunxi (Allwinner) and s3c24xx (old Samsung).

   - The recently added Uniphier platform now uses standard PSCI methods
     for SMP booting and we remove support for old bootloader versions
     that did not support it yet.

   - In sunxi, we gain support for the "Nextthing GR8" SoC, which is a
     close relative of the Allwinner A13 and R8 chips.

   - PXA completes its move over to the generic dmaengine framework and
     removes its old private API

   - mach-bcm gains support for BCM47189/BCM53573, their first ARM SoC
     with integrated 802.11ac wireless networking"
