Subject: [PATCH v4 4/4] drm/panfrost: Register devfreq cooling and attempt to add Energy Model
Date: Mon, 9 Mar 2020 13:41:17 +0000 [thread overview]
Message-ID: <20200309134117.2331-5-lukasz.luba@arm.com> (raw)
In-Reply-To: <20200309134117.2331-1-lukasz.luba@arm.com>
Register devfreq cooling device and attempt to register Energy Model. This
will add the devfreq device to the Energy Model framework. It will create
a dedicated and unified data structures used i.e. in thermal framework.
The last NULL parameter indicates that the power model is simplified and
created based on DT 'dynamic-power-coefficient', voltage and frequency.
