Hi. This happened because we're using device trees from upstream (Linux) 
now, and they do not have entries for the thermal sensor.

I made a little work-in-progress patch:

That uses the configuration proposed for Linux: 
https://lkml.org/lkml/2018/1/28/406
But it currently fails in aw_thermal_init.

And anyway, reading the sensor correctly depends on reading thermal 
calibration data, which is currently in progress:
