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

Pull ARM SoC cleanups from Olof Johansson:
 "This branch contains code cleanups, moves and removals for 3.12.

  There's a large number of various cleanups, and a nice net removal of
  13500 lines of code.

  Highlights worth mentioning are:

   - A series of patches from Stephen Boyd removing the ARM local timer
     API.
   - Move of Qualcomm MSM IOMMU code to drivers/iommu.
   - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM
     driver and switching over to the drivers/pwm one.
   - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).

  There's also a move of a header file out of include/linux/i2c/ to
  platform_data, where it really belongs.  It touches mostly ARM
  platform code for include changes so we took it through our tree"
