[PATCH 3/6] ARM: tegra: Add thermal trip points for Jetson TK1

From: Mikko Perttunen
Date: Fri Jun 27 2014 - 04:12:43 EST


This adds critical trip points to the Jetson TK1 device tree.
The device will do a controlled shutdown when either the CPU, GPU
or MEM thermal zone reaches 101 degrees Celsius.
