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

Pull arm-soc power management changes from Arnd Bergmann:
 "These are various power management related changes, mainly concerning
  cpuidle on i.MX and OMAP, as well as a the move of the omap
  smartreflex driver to live in the power subsystem."

Fix up conflicts in arch/arm/mach-{imx/mach-imx6q.c,omap2/prm2xxx_3xxx.h}
