Hi Rafael,

I submitted the V6 version with all comments from Viresh addressed.

Hi Kukjin Kim,

Any suggestion on how this patch should be merged. In my opinion it
should go via Rafael's tree as this patch uses some fixes present in
Rafael's tree like modified cpufreq_notify_transition API.

Thanks,
Amit Daniel
