Subject: [PATCH v4 07/11] arm64: tegra: set critical trips for Tegra132
Date: Mon, 9 May 2016 14:54:00 +0800 [thread overview]
Message-ID: <1462776844-2152-8-git-send-email-wni@nvidia.com> (raw)
In-Reply-To: <1462776844-2152-1-git-send-email-wni@nvidia.com>
Set general "critical" trip temperatures for cpu, gpu, mem and pllx
thermal zones on Tegra132, these trips can trigger shut down or reset.
Signed-off-by: Wei Ni <wni@nvidia.com>
