    Subject[PATCH 0/3] netdev/of/phy: MDIO bus multiplexer support.
    Date
    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.

    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.

    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.
