When you MAC driver is posted to netdev, the DT binding will get reviewed. And i expect int-phy-handle will be rejected. Often the first dtsi and dts submission for a new SoC have just the CPUs and the serial port, since none of the other drivers have been reviewed yet, unless they reuse existing drivers. The additional nodes are then added one by one as the drivers get accepted. Andrew
