Subject: [PATCH 0/3] netdev/of/phy: MDIO bus multiplexer support.
Date: Wed, 31 Aug 2011 13:01:43 -0700 [thread overview]
Message-ID: <1314820906-14004-1-git-send-email-david.daney@cavium.com> (raw)
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.
