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>;

};
