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

Pull ARM SoC cleanups from Olof Johansson:
 "A large cleanup branch this release, with a healthy 10k negative line
  delta.

  Most of this is removal of legacy (non-DT) support of shmobile
  platforms.  There is also removal of two non-DT platforms on OMAP, and
  the plat-samsung directory is cleaned out by moving most of the
  previously shared-location-but-not-actually-shared files from there to
  the appropriate mach directories instead.

  There are other sets of changes in here as well:

   - Rob Herring removed use of set_irq_flags under all platforms and
     moved to genirq alternatives

   - a series of timer API conversions to set-state interface

   - ep93xx, nomadik and ux500 cleanups from Linus Walleij

   - __init annotation fixes from Nicolas Pitre

   + a bunch of other changes that all add up to a nice set of cleanups"
