Hi Andrew,
Yes, from my understanding an mdio node is not explicitly needed as it
just uses "phy-handle".
However, I think it makes more sense to place the phy within an mdio
node instead of directly under the controller node. This is based off
of 5ecd39d1bc4b ("dt-bindings: net: convert emac_rockchip.txt to YAML"),
in which the same decision was made ("Add mdio sub node"), also during a
text -> yaml conversion.
