Shenoy" Date: Thu, 25 Apr 2024 16:07:51 +0800 Subject: [PATCH] cpufreq: amd-pstate: Document *_limit_* fields in struct amd_cpudata 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 Acked-by: Huang Rui Fixes: febab20caeba("cpufreq/amd-pstate: Fix scaling_min_freq and scaling_max_freq update") Reviewed-by: Li Meng Tested-by: Dhananjay Ugwekar Signed-off-by: Gautham R.
