Merge branch 'next/cleanup-exynos-clock' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup

* 'next/cleanup-exynos-clock' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: EXYNOS: Add clock register addresses for EXYNOS4X12 bus devfreq driver
  ARM: EXYNOS: add clock registers for exynos4x12-cpufreq
  PM / devfreq: update the name of EXYNOS clock registers that were omitted
  PM / devfreq: update the name of EXYNOS clock register
  ARM: EXYNOS: change the prefix S5P_ to EXYNOS4_ for clock
  ARM: EXYNOS: use static declaration on regarding clock
  ARM: EXYNOS: replace clock.c for other new EXYNOS SoCs
  (includes an update to v3.3-rc6)
