-Properties for an MDIO bus multiplexer found in Broadcom iProc based SoCs.
-
-This MDIO bus multiplexer defines buses that could be internal as well as
-external to SoCs and could accept MDIO transaction compatible to C-22 or
-C-45 Clause. When child bus is selected, one needs to select these two
-properties as well to generate desired MDIO transaction on appropriate bus.
-
-Required properties in addition to the generic multiplexer properties:
-
-MDIO multiplexer node:
-- compatible: brcm,mdio-mux-iproc.
-
-Every non-ethernet PHY requires a compatible so that it could be probed based
-on this compatible string.
-
-Optional properties:
-- clocks: phandle of the core clock which drives the mdio block.
-
-Additional information regarding generic multiplexer properties can be found
-at- Documentation/devicetree/bindings/net/mdio-mux.yaml

-               mdio_mux_iproc: mdio-mux@66020000 {
