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

Pull arm-soc clk changes from Arnd Bergmann:
 "Clock support is moving to the clk subsystem.  These tegra, omap and
  imx changes are for code that is still platform specific and not (yet)
  part of that subsystem."

Fix up conflicts in arch/arm/mach-{imx/clk-imx51-imx53.c,omap2/Makefile}
