Changes since v10:
- Rebased on top of v3.18-rc1

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 patch series is based and tested on v3.18-rc1 and depends on the patch
- "clk: exynos4: remove duplicate div_core2 divider clock instantiation"
(http://www.mail-archive.com/linux-samsung-soc at vger.kernel.org/msg34859.html) This patch has been merged in "arm-soc/samsung/dt3" branch of arm-soc tree.

That patch actually went through clock tree, but it doesn't matter, because AFAIK all the dependencies for this series are already in 3.18-rc1. I'll try to apply it in next days

Thanks. The patch "clk: exynos4: remove duplicate div_core2 divider clock instantiation" is not available in 3.18-rc1. So for testing, I picked this patch from samsung/dt3 branch from arm-soc tree.
