Subject: [PATCH v1 6/7] ARM: tegra: nexus7: Enable memory frequency thermal throttling using ACTMON
Date: Tue, 11 May 2021 00:10:07 +0300 [thread overview]
Message-ID: <20210510211008.30300-7-digetx@gmail.com> (raw)
In-Reply-To: <20210510211008.30300-1-digetx@gmail.com>
The ACTMON module monitors activity of memory clients and then devfreq
driver makes decisions about a required memory frequency based on info
from ACTMON. Add ACTMON device to the thermal zone of Nexus 7 in order
to use it as a cooling device which throttles memory freq on overheat.
