So in this case, I already tested this yesterday, it does not work, basically because the for loop just after of_mdiobus_register is never executed, probably because new_bus->phy_map is not populated, which is not the case by calling mdiobus_register for example. of_mdiobus_register seems to populate this array of phys only for subnodes found in the devicetree...
