title: MDIO bus multiplexer found in Broadcom iProc based SoCs.

description:
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.
