3 This MDIO bus multiplexer defines buses that could be internal as well as
4 external to SoCs and could accept MDIO transaction compatible to C-22 or
5 C-45 Clause. When child bus is selected, one needs to select these two
6 properties as well to generate desired MDIO transaction on appropriate bus.
8 Required properties in addition to the generic multiplexer properties:
