Agreed. Those numbers are the SoC default values. It looks like the thresholds should be defined in a thermal-zones node in the dts, but there is none defined in sun8i-h3.dtsi. We'll have to come up with some reasonable defaults, add them to our dts, and then add support for reading the trip points to the aw_thermal driver. Cheers, Jared
