Subject: [RFC PATCH v3 3/5] thermal: Add interface to cooling devices to handle governor change
Date: Wed, 6 Apr 2022 23:08:07 +0100 [thread overview]
Message-ID: <20220406220809.22555-4-lukasz.luba@arm.com> (raw)
In-Reply-To: <20220406220809.22555-1-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.
