Some ethernet controllers, such as cadence's macb, have an embedded MDIO.
For this reason, the ethernet PHY nodes are not under an MDIO bus, but
directly under the ethernet node.

Hi Codrin

That is deprecated. It causes all sorts of problems putting PHY nodes
in the MAC without a container.

Please fix macb to look for an mdio node, and place your fixed link
inside it.

Seems wrong.

fixed links have never needed to be under a mdio node - see
Documentation/devicetree/bindings/net/ethernet-controller.yaml

fixed-link is a child of the MAC controller, not of a mdio node.
