Re: [PATCH net-next 11/13] net: dsa: sja1105: register the MDIO buses for 100base-T1 and 100base-TX

quoted

It however sounds like you have the two busses one level deeper?

It would be good if you document this as part of the binding.

Yes, it looks like this:

	ethernet-switch@2 {
		compatible = "nxp,sja1110a";

		ethernet-ports {
			...
		};

		mdio {
			#address-cells = <1>;
			#size-cells = <0>;

			mdio@0 {
				reg = <0>;
				compatible = "nxp,sja1110-base-t1-mdio";
				#address-cells = <1>;
				#size-cells = <0>;

				sw2_port5_base_t1_phy: ethernet-phy@1 {
					compatible = "ethernet-phy-ieee802.3-c45";
					reg = <0x1>;
				};

				...
			};

We should run this by Rob.

That is probably not the intention of
Documentation/devicetree/bindings/net/mdio.yaml, it works because of
additionalProperties: true

What meaning does reg have, in mdio@0?
