Subject: [PATCH v7 15/15] drm/panfrost: Register devfreq cooling and attempt to add Energy Model
Date: Mon, 11 May 2020 12:19:12 +0100
Message-ID: <20200511111912.3001-16-lukasz.luba@arm.com> (raw)
In-Reply-To: <20200511111912.3001-1-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.
