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
