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

Pull ARM SoC cleanups from Arnd Bergmann:
 "A large number of cleanups, all over the platforms.  This is dominated
  largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
  others moving code out of arch/arm into more appropriate subsystems.

  The clocksource and irqchip drivers are now abstracted to the point
  where platforms that are already cleaned up do not need to even
  specify the driver they use, it can all get configured from the device
  tree as we do for normal device drivers.  The clocksource changes
  basically touch every single platform in the process.

  We further clean up the use of platform specific header files here,
  with the goal of turning more of the platforms over to being
  "multiplatform" enabled, which implies that they cannot expose their
  headers to architecture independent code any more.

  It is expected that no functional changes are part of the cleanup.
  The overall reduction in total code lines is mostly the result of
  removing broken and obsolete code."
