Re: [PATCH] lan743x: Added fixed_phy support / Question regarding proper devicetree

Working status: I added fixed_phy support to the Microchip lan743x ethernet driver and for upstream contribution I need to make it runtime configurable via the device tree.

Question:

There are, amongst other, the following devices on my target (i.mx6): 
/soc/aips-bus@2100000/ethernet@2188000
/soc/pcie@1ffc000

Where would I put my additional lan743x ethernet device in the device tree ?

a) /ethernet@0
    (Just a new root node.

b) /pci@0/ethernet@0
    (I would „invent“ pci@0 to reflect that the lan7431 is sitting on the first pci slot.

c) /soc/pcie@1ffc000/ethernet@0
    (That doesn’t feel right to me, it’s not a soc property. Or is it ?

Example:

        pci0 {
                ethernet@0 {
                        compatible = "rmtl-meu-hl“;
                        status = "okay“;
                        phy-connection-type = "rgmii“;
                        
                        fixed-link {
                                speed = <100>;
                                full-duplex;
                        };
                };
                
        }

Thanks a lot,
