Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Olof Johansson:
 "This merge window brings a good size of cleanups on various platforms.
  Among the bigger ones:

   - Removal of Samsung s5pc100 and s5p64xx platforms.  Both of these
     have lacked active support for quite a while, and after asking
     around nobody showed interest in keeping them around.  If needed,
     they could be resurrected in the future but it's more likely that
     we would prefer reintroduction of them as DT and
     multiplatform-enabled platforms instead.

   - OMAP4 controller code register define diet.  They defined a lot of
     registers that were never actually used, etc.

   - Move of some of the Tegra platform code (PMC, APBIO, fuse,
     powergate) to drivers/soc so it can be shared with 64-bit code.
     This also converts them over to traditional driver models where
     possible.

   - Removal of legacy gpio-samsung driver, since the last users have
     been removed (moved to pinctrl)

  Plus a bunch of smaller changes for various platforms that sort of
  dissapear in the diffstat for the above.  clps711x cleanups, shmobile
  header file refactoring/moves for multiplatform friendliness, some
  misc cleanups, etc"
