I'll send out pull-request soon. On Krzysztof Kozlowski's reply, dts patches will be merged on samsung-soc tree. and then the clock patches about exynos5420 was already merged to samsung-clk tree by Sylwester. Only devfreq patches should be merged on devfreq tree. We already discussed this topic on offline. I expect that you will again handle this patchset according to reply of both Krzysztof and me.
