Subject: [PATCH v1 4/7] dt-bindings: devfreq: tegra30-actmon: Add cooling-cells
Date: Tue, 11 May 2021 00:10:05 +0300 [thread overview]
Message-ID: <20210510211008.30300-5-digetx@gmail.com> (raw)
In-Reply-To: <20210510211008.30300-1-digetx@gmail.com>
The ACTMON watches activity of memory clients. Decisions about a minimum
required frequency are made based on the info from ACTMON. We can use
ACTMON as a thermal cooling device by limiting the required frequency.
Document new cooling-cells property of NVIDIA Tegra ACTMON hardware unit.
