7 title: MDIO bus multiplexer found in Broadcom iProc based SoCs.
10 - Florian Fainelli <[email protected]>
13 This MDIO bus multiplexer defines buses that could be internal as well as
14 external to SoCs and could accept MDIO transaction compatible to C-22 or
15 C-45 Clause. When child bus is selected, one needs to select these two
16 properties as well to generate desired MDIO transaction on appropriate bus.
