Subject: Re: [PATCH v6 01/21] PM / devfreq: exynos: Add generic exynos bus
 frequency driver

>   
>  This patch adds the generic exynos bus frequency driver for AMBA AXI bus
> of sub-blocks in exynos SoC with DEVFREQ framework. The Samsung Exynos SoC
> have the common architecture for bus between DRAM and sub-blocks in SoC.
> This driver can support the generic bus frequency driver for Exynos SoCs.
> 
> In devicetree, Each bus block has a bus clock, regulator, operation-point
> and devfreq-event devices which measure the utilization of each bus block.
