Merge tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC late changes from Arnd Bergmann:
 "These are changes that arrived a little late before the merge window
  or that have multiple dependencies on previous branches so they did
  not fit into one of the earlier ones.  There are 10 branches merged
  here, a total of 39 non-merge commits.  Contents are a mixed bag for
  the above reasons:

   * Two new SoC platforms: ST microelectronics stixxxx and the TI
     'Nspire' graphing calculator.  These should have been in the 'soc'
     branch but were a little late
   * Support for the Exynos 5420 variant in mach-exynos, which is based
     on the other exynos branches to avoid conflicts.
   * Various small changes for sh-mobile, ux500 and davinci
   * Common clk support for MSM"
