+ help
+ Enable this option for integrated thermal management support on NVIDIA
+ Tegra systems-on-chip. The driver supports four thermal zones
+ (CPU, GPU, MEM, PLLX). Cooling devices can be bound to the thermal
+ zones to manage temperatures. This option is also required for the
+ emergency thermal reset (thermtrip) feature to function.
