Changes since v11:
- Rebased on top of git://linuxtv.org/snawrocki/samsung.git for-v3.19-exynos-clk

This patch series removes the use of Exynos4210 and Exynos5250 specific cpufreq
drivers and enables the use of cpufreq-dt driver for these platforms. This
series also enables cpufreq support for Exynos5420 using arm_big_little cpufreq
driver.

This series is based on the following branch.
git://linuxtv.org/snawrocki/samsung.git for-v3.19-exynos-clk

This series depends on the following patch which can be picked from
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git samsung/dt
e540920cf21c (ARM: dts: add CPU nodes for Exynos4 SoCs).

This patch series has been tested on Exynos4210/5250/5420 based boards.
Tomasz Figa had plans to take this in the Samsung clock tree for v3.19
(http://www.spinics.net/lists/linux-samsung-soc/msg37933.html).
Sylwester, could you consider to merge this in your tree?

Thomas Abraham (6):
  clk: samsung: add infrastructure to register cpu clocks
  clk: samsung: add cpu clock configuration data and instantiate cpu clock
  ARM: dts: Exynos: add CPU OPP and regulator supply property
  ARM: Exynos: switch to using generic cpufreq driver for Exynos4210/5250/5420
  cpufreq: exynos: remove exynos4210/5250 specific cpufreq driver support
  clk: samsung: remove unused clock aliases and update clock flags
