This was merged, while I was AFK, so the ship has sailed, but let me
state here objection for any future discussions:

NAK, this is not a thermal sensor. The commit msg explains what they
want to achieve, but that's not a valid reason to add property from
different class of devices.

This is some hardware/temperature monitoring device or power supply, not
part of SoC, not integrated into any SoC thermal zone. Calling it
thermal sensor is huge stretch and inappropriate hardware description
leading to next patches like calling it a SoC cooling device, instead of
simple power supply (for which we have bindings!).

Best regards,
Krzysztof
