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> --- v5: added cooling-maps nodes
OK. But no cooling map entry in it. What was the reason again you don't need/want to add the maps?
