Merge tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: More SoC support updates" from Olof Johansson:
"This branch contains a handful of updates of SoC base code that had
dependencies on other external trees that have now been merged:
* Support for the new EXYNOS5250 SoC from Samsung
* SMP and power domain support for Tegra3 from NVIDIA
* ux500 updates for exporting SoC information through sysfs"
Fix up trivial merge conflicts as per Olof.
* tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (30 commits)
