Subject: Re: [PATCH v4 04/20] ARM: dts: Add DMC bus frequency for
 exynos3250-rinato/monk

>   
>  This patch adds the DMC (Dynamic Memory Controller) bus frequency node

> frequency support the DVFS (Dynamic Voltage Frequency Scaling) feature

> 
> The devfreq-events (ppmu_dmc0*) can monitor the utilization of DMC bus
> on runtime and the buck1_reg (VDD_MIF power line) supplies the power to
