2a5cf8016c of/mdio: Staticise !CONFIG_OF stubs
The !CONFIG_OF stubs aren't static so if multiple files include the
header with this configuration then the linker will see multiple
definitions of the stubs.

f9dc9ac516 of/mdio: Add dummy functions in of_mdio.h.
This patch adds dummy functions in of_mdio.h, so that driver need not
ifdef there code with CONFIG_OF.

2510602200 netdev/of/phy: New function: of_mdio_find_bus().
Add of_mdio_find_bus() which allows an mii_bus to be located given its
associated the device tree node.

This is needed by the follow-on patch to add a driver for MDIO bus
multiplexers.

The of_mdiobus_register() function is modified so that the device tree
node is recorded in the mii_bus.  Then we can find it again by
iterating over all mdio_bus_class devices.

Because the OF device tree has now become an integral part of the
kernel, this can live in mdio_bus.c (which contains the needed
mdio_bus_class structure) instead of of_mdio.c.

24c30dbbcd of/mdio: Add support function for Ethernet fixed-link property
Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet
device drivers.  The "OF MDIO rework" patches removed most of the
support. Instead of re-adding fixed-link stuff to the drivers, this
patch adds a support function for parsing the fixed-link property
and obtaining a dummy phy to match.

Note: the dummy phy handling in arch/powerpc is a bit of a hack and
needs to be reworked.  This function is being added now to solve the
regression in the Ethernet drivers, but it should be considered a
temporary measure until the fixed link handling can be reworked.

8bc487d150 openfirmware: Add OF phylib support code
Add support for parsing the device tree for PHY devices on an MDIO bus.
Currently many of the PowerPC ethernet drivers are open coding a solution
for reading data out of the device tree to find the correct PHY device.
This patch implements a set of common routines to:

a) let MDIO bus drivers register phy_devices described in the tree, and
b) let MAC drivers find the correct phy_device via the tree.
