Actually it's just "label" as seen from the code and the binding. Though it would make sense to have labels (pluralis) as it can be more than one and accompanies "gpios" which is plural. Rob: what is the pattern here? (Grep the existing bindings to check how multiple labels are handled in other subsystems...)

Is this what we want?
