From ed7eac3371f39a2c9f4b594dbca04c50fff4739a Mon Sep 17 00:00:00 2001 From: Mikko Perttunen Date: Fri, 26 Sep 2014 12:43:12 +0300 Subject: [PATCH] ARM: tegra: Add thermal trip points for Jetson TK1 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.
