1MDIO on GPIOs

3Currently defined compatibles:
4- virtual,gpio-mdio
5
6MDC and MDIO lines connected to GPIO controllers are listed in the
7gpios property as described in section VIII.1 in the following order:
8
9MDC, MDIO.
10
11Note: Each gpio-mdio bus should have an alias correctly numbered in "aliases"
12node.

14Example:
15
16aliases {
17	mdio-gpio0 = &mdio0;
18};
19
20mdio0: mdio {
21	compatible = "virtual,mdio-gpio";
22	#address-cells = <1>;
23	#size-cells = <0>;
24	gpios = <&qe_pio_a 11
25		 &qe_pio_c 6>;
26};
