Subject: [RFC PATCH v2 4/6] thermal: Add interface to cooling devices to handle governor change
Date: Tue, 6 Jul 2021 14:18:26 +0100 [thread overview]
Message-ID: <20210706131828.22309-5-lukasz.luba@arm.com> (raw)
In-Reply-To: <20210706131828.22309-1-lukasz.luba@arm.com>
Add interface to cooling devices to handle governor change, to better
setup internal needed structures or to cleanup them. This interface is
going to be used by thermal governor Intelligent Power Allocation (IPA).
which requires to setup monitoring mechanism in the cpufreq cooling
devices.
