The talk was in context of bindings, not about changing all existing
users thus affecting DTS. What's more, to me "skin-temp-thermistor" is
quite generic name, maybe "thermistor" would be more and reflects the
purpose of the node, so it was more or less fine.

Anyway I am against such changes without expressing it in the bindings.
