I am just describing each lane of the SerDes block so that each ethernet dts node references it directly. Since I am new to the generic PHY infrastructure I was using the COMPHY for the Marvell MVEBU SoCs (phy-mvebu-comphy.txt) as a loose example. Each lane there is described as a different child node as well. The only difference from the COMPHY is that Lynx 28G does not need #phy-cells = <1> to reference the input port, we just use '#phy-cells = <0>' on each lane. What is wrong with this approach? Or better, is there an easier way to do this? > > > + > > + additionalProperties: false > > + > > +additionalProperties: false > > + > > +examples: > > + - | > > + soc { > > + #address-cells = <2>; > > + #size-cells = <2>; > > + serdes_1: serdes_phy@1ea0000 { > > node name just "phy" Sure.
