v2: Update bindings to use "reg" and "mdio-parent-bus" insutead of "cell-index" and "parent-bus"
v1:
We have several different boards with a multiplexer in the MDIO bus. 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.
David Daney (3): netdev/of/phy: New function: of_mdio_find_bus(). netdev/of/phy: Add MDIO bus multiplexer support. netdev/of/phy: Add MDIO bus multiplexer driven by GPIO lines.
