Like as hs/ss/aux, to make the user know to use 6360's tcpc? I check the style in connector/usb-connect.yaml Do I also need to replace two space instead of one tab in the binding example? > > > > > + compatible = "usb-c-connector"; > > > + label = "USB-C"; > > > + data-role = "dual"; > > > + power-role = "dual"; > > > + try-power-role = "sink"; > > > + source-pdos = <PDO_FIXED(5000, 1000, PDO_FIXED_DUAL_ROLE | PDO_FIXED_DATA_SWAP)>; > > > + sink-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_DUAL_ROLE | PDO_FIXED_DATA_SWAP)>; > > > + op-sink-microwatt = <10000000>; > > > + }; > > > + }; > > > + }; > > > + }; > > > +... > > > -- > > > 2.7.4 > > >
