1MDIO on GPIOs
2
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.
13
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};
