I'm not a DT maintainer, but I think they should, e.g. to mention which port is the input and which is the output. > + > + port@0 { > + reg =3D <0>; > + endpoint { > + remote-endpoint =3D <&dcss_out>; > + }; > + }; > + > + port@1 { > + reg =3D <1>; > + endpoint { > + data-lanes =3D <2 1 0 3>; Having a remote-endpoint property would be nice here, to make the example more complete.
