[PATCH v10 1/8] cpufreq: amd-pstate: Document *_limit_* fields in struct amd_cpudata
Posted by Perry Yuan 1 year, 10 months ago
From: "Gautham R. Shenoy" <gautham.shenoy@amd.com>

The four fields of struct cpudata namely min_limit_perf,
max_limit_perf, min_limit_freq, max_limit_freq introduced in the
commit febab20caeba("cpufreq/amd-pstate: Fix scaling_min_freq and
scaling_max_freq update") are currently undocumented

Add comments describing these fields

Fixes: febab20caeba("cpufreq/amd-pstate: Fix scaling_min_freq and scaling_max_freq update")

I think we should use "performance" instead of "perf" in the comments.

With that fixed, patch is Acked-by: Huang Rui <ray.huang@amd.com>
