Subject: [PATCH v3 0/3] netdev/of/phy: MDIO bus multiplexer support.
Date: Mon, 16 Apr 2012 18:03:25 -0700 [thread overview]
Message-ID: <1334624608-26667-1-git-send-email-ddaney.cavm@gmail.com> (raw)
From: David Daney <david.daney@cavium.com>
This code has been working well for about six months on a couple of
different configurations (boards), so I thought it would be a good
time to send it out again, and I hope get it on the path towards
merging.
v3: Update binding to use "mdio-mux-gpio" compatible property.
Cleanups suggested by Grant Likely. Now uses the driver probe
deferral mechanism if GPIOs or parent bus not available.
v2: Update bindings to use "reg" and "mdio-parent-bus" instead 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.
