-MDIO on GPIOs
-
-Currently defined compatibles:
-- virtual,gpio-mdio
-- microchip,mdio-smi0
-
-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.
-
-Note: Each gpio-mdio bus should have an alias correctly numbered in "aliases"
-node.
-
-Example:
-
-aliases {
-	mdio-gpio0 = &mdio0;
-};
-
-mdio0: mdio {
-	compatible = "virtual,mdio-gpio";
-	#address-cells = <1>;
-	#size-cells = <0>;
-	gpios = <&qe_pio_a 11
-		 &qe_pio_c 6>;
-};
