Subject: [PATCH v4 08/11] arm64: tegra: set hot trips for Tegra132
Date: Mon, 9 May 2016 14:54:01 +0800	[thread overview]
Message-ID: <1462776844-2152-9-git-send-email-wni@nvidia.com> (raw)
In-Reply-To: <1462776844-2152-1-git-send-email-wni@nvidia.com>

Enable throttle function for SOC_THERM.
Set "hot" trips for cpu and gpu thermal zones, which
can trigger the SOC_THERM hardware throttle.
