    1 MDIO on GPIOs
    2 
    3 Currently defined compatibles:
    4 - virtual,gpio-mdio
    5 - microchip,mdio-smi0
    6 
    7 MDC and MDIO lines connected to GPIO controllers are listed in the
    8 gpios property as described in section VIII.1 in the following order:
    9 
   10 MDC, MDIO.
   11 
   12 Note: Each gpio-mdio bus should have an alias correctly numbered in "aliases"
   13 node.
   14 
   15 Example:
   16 
   17 aliases {
   18         mdio-gpio0 = &mdio0;
   19 };
   20 
   21 mdio0: mdio {
   22         compatible = "virtual,mdio-gpio";
   23         #address-cells = <1>;
   24         #size-cells = <0>;
   25         gpios = <&qe_pio_a 11
   26                  &qe_pio_c 6>;
   27 };
