Almost, the "reg" property applies to the MDIO child nodes: the Ethernet PHYs/MDIO devices. For the MDIO controller itself, the "reg" property, if specified, would be relative to the Ethernet controller's base register address. Please drop this property's description here.

+ phy-handle = <ðphy>;
+ clocks = <&sys_clk 6>;
+ resets = <&sys_rst 6>;
+ local-mac-address = [00 00 00 00 00 00];
+ mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ ethphy: ethphy at 1 {
+ reg = <1>;
