Hi Katsuhiro It makes it less ambiguous if there is a phy-handle. It is then very clear which PHY should be used. For a development board, which people can be tinkering around with, there is a chance they add a second PHY to the MDIO bus, or an Ethernet switch, etc. Without explicitly listing the PHY, it might get the wrong one. However this is generally a problem if phy_find_first() is used. I think in this case, something is setting priv->plat->phy_addr, so it is also clearly defined which PHY to use. Andrew
