The rktemp driver provides support for the temperature sensor found on the Rockchip RK3288, RK3328 and RK3399 SoCs. It configures the SoC to reset itself if the temperature raises above a certain temperature to protect it from damage caused by overheating.

Sensor values are made available through the sysctl(8) interface.
