Summary

This diff adds support for the thermal sensor found in the A83T SoC.

The A83T thermal sensor controller has three thermal sensors. Sensor 0 corresponds to CPU cluster 0, sensor 1 corresponds to CPU cluster 1, and sensor 2 corresponds to the GPU. The sensor values are exported via sysctl.

Calibration data is obtained from SRAM found in the Secure ID module.
