Subject: Re: [PATCH RFC 8/8] ARM: dts: exynos: Add ASV tables for exynos5422/5800

Hi Sylwester,

As per my knowledge HK soc introduce this table to support
overclocking of cpufreq for Odroid XU3 XU4 family for boards.

ARM Cortex-A15 Quad CPU (Eagle) 1800 to 2000
ARM Cortex-A7 Quard CPU (Kingfisher) 1400 to 1500

For Exynos5422  below table
asv-table-[0-3]  AVS range from 200 to 2100
asv-table-[100-103] AVS range from 200 to 1500.

Are these setting stable for this board to cover clock the cpu now.

Can you also enable support for this clk-exynos5420.c
For example exynos5800_eglclk_d and exynos5420_kfcclk_d table.

Also can you update exynos5420.dtsi  following opp table
For example cluster_a15_opp_table and cluster_a7_opp_table opt binding.

To make this work synchronously with AVS.

Best Regards
-Anand
