Thanks for the swift response.

I also found that both gfar_init (in gianfar.c) and=20
gfar_mdio_init (in gianfar_mii.c) are called but the probe=20
handlers of either of these devices are not executed.
=20
What am I missing?

Don't find any obvious problem.  I suggest you to debug gfar_of_init()
in arch/powerpc/sysdev/fsl_soc.c to see if it works correctly.

That fn doesn't exist in the dev tree I'm using (commit 103f194f3ccf4684254=
8eb52e607167b6d4951ef)

The driver is now initialised through of_device. I can't figure out how the=
 probe handler is invoked.
