Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm soc-specific updates from Arnd Bergmann:
"This is stuff that does not fit well into another category and in
particular is not related to a particular board. The largest part in
here is extending the am33xx support in the omap platform."
Fix up trivial conflicts in arch/arm/mach-{imx/mach-mx35_3ds.c, tegra/Makefile}
