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. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
