Subject: [PATCH v2 4/4] devfreq/drivers/panfrost: Use devfreq cooling device registration
Date: Fri,  5 Mar 2021 18:03:37 +0100	[thread overview]
Message-ID: <20210305170338.13647-4-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20210305170338.13647-1-daniel.lezcano@linaro.org>

The devfreq core code is able to register the devfreq device as a
cooling device if the 'is_cooling_device' flag is set in the profile.

Use this flag and remove the cooling device registering code.

Tested on rock960.
