It registers as temperature sensor with the thermal subsystem. The documentation
of #thermal-sensor-cells states that the property is mandatory and "... Will be
0 on sensor nodes with only a single sensor". I don't claim to understand how
this is supposed to work, but the thermal subsystem code looking for it does
seem to suggest that the property is mandatory, even if there is only a single
sensor.

Thanks,
