Subject: Re: [PATCHv7 04/10] devfreq: event: Add exynos-ppmu devfreq-event
 driver

>   
>  This patch adds exynos-ppmu devfreq-event driver to get performance data
> of each IP for Samsung Exynos SoC. These event from Exynos PPMU provide
> useful information about the behavior of the SoC that you can use when
> analyzing system performance, and made visible and can be counted using
> logic in each IP.
