Merge tag 'tags/cleanup2-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late cleanups from Arnd Bergmann:
"These could not be part of the first cleanup branch, because they
either came too late in the cycle, or they have dependencies on other
branches. Important changes are:
- The integrator platform is almost multiplatform capable after some
reorganization (Linus Walleij)
- Minor cleanups on Zynq (Michal Simek)
- Lots of changes for Exynos and other Samsung platforms, including
further preparations for multiplatform support and the clocks
bindings are rearranged"
