Subject: [PATCH V3 3/3] thermal/cpu-cooling: Update thermal pressure in case of a maximum frequency capping
Date: Tue, 16 Apr 2019 15:38:41 -0400 [thread overview]
Message-ID: <1555443521-579-4-git-send-email-thara.gopinath@linaro.org> (raw)
In-Reply-To: <1555443521-579-1-git-send-email-thara.gopinath@linaro.org>
Enable cpufreq cooling device to update the thermal pressure in
event of a capped maximum frequency or removal of capped maximum
frequency.
