Subject: [PATCH v1 7/7] ARM: tegra: ouya: Enable memory frequency thermal throttling using ACTMON
Date: Tue, 11 May 2021 00:10:08 +0300	[thread overview]
Message-ID: <20210510211008.30300-8-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 Ouya in order to
use it as a cooling device which throttles memory freq on overheat.
