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"
