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" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (55 commits) ARM: ux500: remove deleted file from Makefile ARM: ep93xx: Disable TS-72xx watchdog before uncompressing ARM: ux500: cut some platform data MAINTAINERS: Update for the current location of the bcm2835 tree.
