Though it looks like there's some non-standard ones (-microvolts) in the series. Rob

Ok. Unfortunately most properties in this series use non-standard ones :(. Newer bindings using common properties have already been written in YAML and/or make use of simple-battery. Can we have a warning for this in the dt_binding_check? Maybe something like superfluous $ref for property with standard suffix -- Sebastian
