+MDIO on GPIOs
+
+Currently defined compatibles:
+- virtual,gpio-mdio
+
+MDC and MDIO lines connected to GPIO controllers are listed in the
+gpios property as described in section VIII.1 in the following order:
+
+MDC, MDIO.
+
+Example:
+
+mdio {
+ compatible = "virtual,mdio-gpio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ gpios = <&qe_pio_a 11
+ &qe_pio_c 6>;
+};
