[PATCH v4 4/5] net: stmmac: dwmac-sun8i: choose internal PHY via phy-is-integrated

Do you agree that another mdio_mux_init() must be written ? (taking
a of_node (in our case: mdio-mux) instead of a device)

Yes, you are correct, it is using dev->of_node. So you need to
refactor the code a little, to allow an of_node to be passed.
