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

Browse Source 
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"

Enable support for local timers on SMP platforms, rather then the
legacy IPI broadcast method. Local timers allows the system
accounting to be spread across the timer interval, preventing a
"thundering herd" at every timer tick.
# The GPIO number here must be sorted by descending number. In case of
# a multiplatform kernel, we just want the highest value required by the
# selected platforms.
