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

Pull arm-soc clock driver changes from Olof Johansson:
 "The new clock subsystem was merged in linux-3.4 without any users,
  this now moves the first three platforms over to it: imx, mxs and
  spear.

  The series also contains the changes for the clock subsystem itself,
  since Mike preferred to have it together with the platforms that
  require these changes, in order to avoid interdependencies and
  conflicts."

Fix up trivial conflicts in arch/arm/mach-kirkwood/common.c (code
removed in one branch, added OF support in another) and
drivers/dma/imx-sdma.c (independent changes next to each other).
