I have tested this on Kirkwood (Sheevaplug eSATA). When using
mv643xx_eth as a module with a built-in mvmdio the GbE port works.
However, when unloading the mv643xx_eth module and loading it again,
the second call to of_platform_bus_probe() results in a warning:
[ 190.542992] WARNING: at fs/sysfs/dir.c:530 sysfs_add_one+0x7c/0xa4()
[ 190.549372] sysfs: cannot create duplicate filename '/devices/ocp.0/f1072000.
ethernet-controller/0.ethernet-port'
(Looks more like a problem of of_platform_bus_probe() than a problem
in the driver?)

If the clock isn't already enabled (mvmdio and mv643xx_eth both built
as modules), a delay seems to be necessary in mv643xx_eth_probe()
after enabling the clock on my hardware. Otherwise the device hangs.
Andrew found the same in the past (see [1]). udelay(50) seems to be
sufficient in my case.

of_phy_connect() returns NULL in case of an error and no ERR_PTR.
