However 1. Patch dependency should not be part of commit message, It simply won't provide any meaningful information when they are merged. 2. Similarly testing platform also is not always put in commit message. So just put them after separator (triple-dash).

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. -Anand Moon On 8 May 2015 at 05:44, Krzysztof Kozlowski <k.kozlowski@samsung.com> wrote: > 2015-05-08 2:48 GMT+09:00 Anand Moon <linux.amoon@gmail.com>: >> Addition of CLK_RECALC_NEW_RATES flag to support Exynos5 cpu clk so that >> correct divider values are re-calculated after both pre/post >> clock notifiers had run for for mout_apll clock and mout_kpll clock. > s/for for/for/ > > Could you precise in commit message the observational effects > *without* this patch?

It does not have to be energy consumption. It may be something else visible, like wrong values for clock rates. I don't know, it is your patch so you should know *what is fixed* (or changed).

Addition of CLK_RECALC_NEW_RATES flag to support Exynos5 cpu clk so that correct divider values are re-calculated after both pre/post clock notifiers had run for for mout_apll clock and mout_kpll clock.
