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"
