Subject: [PATCH v2 0/3] netdev/of/phy: MDIO bus multiplexer support.
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.
