[PATCH v8 0/6] cpufreq: use generic cpufreq drivers for exynos platforms

Changes since v7:
- Fixes suggested by Tomasz Figa.

This patch series removes the use of Exynos4210 and Exynos5250 specific cpufreq
drivers and enables the use of cpufreq-cpu0 driver for these platforms. This
series also enables cpufreq support for Exynos5420 using arm_big_little cpufreq
driver.

This patch series is dependent on two other patches
1. ARM: dts: add CPU nodes for Exynos4 SoCs
   - https://lkml.org/lkml/2014/7/21/315
2. ARM: dts: smdk5250: Specify MAX77686 pmic interrupt
   - http://www.spinics.net/lists/arm-kernel/msg351134.html

Since there are significant changes since v7, the Tested-by and Acked-by tags
for all the patches in this series have been dropped.

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
