From: Gautham R. Shenoy Date: Thu, 25 Apr 2024 08:07:52 +0000 (+0800) Subject: cpufreq: amd-pstate: Document the units for freq variables in amd_cpudata X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4fcfd1954ad305e331b6b4b62de2874fbae61394;p=linux.git cpufreq: amd-pstate: Document the units for freq variables in amd_cpudata The min_limit_freq, max_limit_freq, min_freq, max_freq, nominal_freq and the lowest_nominal_freq members of struct cpudata store the frequency value in khz to be consistent with the cpufreq core.
