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:
"In the SoC branch we normally collect classic arch/arm/mach-*
contents, i.e. C code changes for SoC platforms. This release cycle
the diffstat is quite nice, in that we're removing 3x the amount of
code that's being added.
The main reason for this is that there's a removal of camera drivers
for Freescale i.MX chips (driver was removed so the device
registration isn't needed any more). There's also removal of display
initialization code for OMAP that is no longer needed.
The rest are mostly minor tweaks and cleanups; constification on
Samsung platforms, cleanup of ux500 platform data, purge of other
unused platform data/device seutp on i.MX and other good stuff.
New SoC support this cycle is for two Allwinner platforms, H2+ and
V3s"
