-Properties for an MDIO bus multiplexer/switch controlled by GPIO pins.
-
-This is a special case of a MDIO bus multiplexer. One or more GPIO
-lines are used to control which child bus is connected.
-
-Required properties in addition to the generic multiplexer properties:
-
-- compatible : mdio-mux-gpio.
-- gpios : GPIO specifiers for each GPIO line. One or more must be specified.
-
-
-Example :
-
- /* The parent MDIO bus. */
- smi1: mdio@1180000001900 {
- compatible = "cavium,octeon-3860-mdio";
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0x11800 0x00001900 0x0 0x40>;
- };
-
- /*
- An NXP sn74cbtlv3253 dual 1-of-4 switch controlled by a
- pair of GPIO lines. Child busses 2 and 3 populated with 4
- PHYs each.
