There is an MDIO bus controller connected to a switching device with several child MDIO busses. Everything is wired up using device tree bindings. 1/3 - New of_mdio_find_bus() function used to help configuring the driver topology. 2/3 - MDIO bus multiplexer framework. 3/3 - A driver for a GPIO controlled multiplexer. I have an additional patch I am working on for an I2C controlled multiplexer that I will follow up with once this reaches a mergable state.
