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.
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>;
};
