+Example :

+ smi1: mdio@1180000001900 {
+ compatible = "cavium,octeon-3860-mdio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x11800 0x00001900 0x0 0x40>;
+ };
+
+ /*
+ An NXP sn74cbtlv3253 dual 1-of-4 switch controlled by a
+ pair of GPIO lines. Child busses 2 and 3 populated with 4
+ PHYs each.
+ */
+ mdio-mux {
+ compatible = "cavium,mdio-mux-sn74cbtlv3253", "cavium,mdio-mux";
+ gpios = <&gpio1 3 0>, <&gpio1 4 0>;
+ mdio-parent-bus = <&smi1>;
+ #address-cells = <1>;
+ #size-cells = <0>;This should probably have 'compatible = "nxp,sn74cbtlv3253";' here. Best Regards, Michał Mirosław
