I don't mind using reg or count it from 0, will look up to see if I can find something solid; otherwise, I'll wait for binding doc maintainers' opinions before sending v5. > >+ status = "disabled"; > >+ }; > >+ input2 { > >+ input-id = <0x2>; > >+ shunt-resistor = <5000>; > > I would suggest shunt-resistor-micro-ohms as per > Documentation/devicetree/bindings/property-units.txt. Will change it. Thank you Nicolin
