Subject: [PATCH v1 0/7] Add thermal cooling support to NVIDIA Tegra devfreq
Date: Tue, 11 May 2021 00:10:01 +0300 [thread overview]
Message-ID: <20210510211008.30300-1-digetx@gmail.com> (raw)
Hi,
Some hardware versions of NVIDIA Tegra SoCs support higher freqs and they
are producing much more heat than the other versions. We found that CPU
throttling may be not enough on devices like Asus Transformer TF700T,
which is Tegra30 tablet device. This series adds thermal cooling support
to the NVIDIA Tegra30+ devfreq which cools down SoC by throttling memory
frequency on overheat.
Dmitry Osipenko (7):
PM / devfreq: tegra30: Support thermal cooling
ARM: tegra_defconfig: Enable CONFIG_DEVFREQ_THERMAL
dt-bindings: devfreq: tegra30-actmon: Convert to schema
dt-bindings: devfreq: tegra30-actmon: Add cooling-cells
ARM: tegra: Add cooling cells to ACTMON device-tree node
ARM: tegra: nexus7: Enable memory frequency thermal throttling using
ACTMON
ARM: tegra: ouya: Enable memory frequency thermal throttling using
ACTMON
