+title: MDIO bus multiplexer found in Broadcom iProc based SoCs.
+
+maintainers:
+  - Florian Fainelli <f.fainelli@gmail.com>
+
+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.
