The support for TMP006 is available at driver/iio/temperature

Okay, will take care in v2.

Thanks, I have noticed that out of the 8 temperature sensor bindings,
5 are using 'temp-sensor' as the node name, 2 are using 'temperature-sensor',
and 1 is non-generic. According to this docs generic names recommendation
'temperature-sensor' seems to be ideal node name. Should I also proceed
updating all the temperature sensor's node names to a generic format?
