as6200 is a temperature sensor with a range between -40°C to
125°C degrees and an accuracy of ±0.4°C degree between 0
and 65°C and ±1°C for the other ranges.

If multiple devices have the interrupt you should document it for all of
them IMO.

Hi Conor,

The interrupt hasn't been implemented for tmp101, tmp102 and tmp112 yet.
Should I still add them to the interrupt property? They might be two different
things driver and bindings, but I just wanted to make sure.

Thanks,
Abdel

I don't really care if the driver supports the interrupt on any of the
platforms (including the as6200), if the hardware has an interrupt the
binding should reflect that :)
