Subject: Re: [PATCH] clk samsung exynos5420 add CLK_RECALC_NEW_RATES flag to
 mout_apll and mout_kpll clock.

Hi Krysztof,

Actually the patch is based on https://lkml.org/lkml/2015/4/3/389
I don't know how to measure the energy consumption when compared to
cpufreq-exynos.

I will update the commit log and resend it with you review.
