Some drivers do allow them directly in the MAC node, some drivers optionally allow an mdio sub-node, others enforce an mdio sub-node. The name of the sub-node is also not well defined. So just documenting that the mdio sub-node is mandatory will help people writing device trees for their boards. Andrew
