[PATCH v4 10/11] arm64: tegra: set critical trips for Tegra210

From: Wei Ni <hidden>
Date: 2016-05-09 06:53:39
Also in: linux-pm, linux-tegra, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

Set general "critical" trip temperatures for cpu, gpu, mem and pllx
thermal zones on Tegra210, these trips can trigger shut down or reset.
