Hi Robert

I tried latest next-20160122 on Colibri PXA270 with a previously
working device tree and got the following DM9000 Ethernet driver issue:

[    1.062495] dm9000 8000000.ethernet: insufficient resources
[    1.068439] dm9000 8000000.ethernet: not found (-2).
[    1.073451] dm9000: probe of 8000000.ethernet failed with error -2

Digging deeper I debugged it to a missing interrupt ressource. A
subsequent git bisect blamed your patch changing the initcall level and
indeed just reverting that made it all work again.

I then also noticed the following message upon boot in the failing case
which is probably related:

[    0.175995] irq: no irq domain found for /pxabus/gpio@...00000 !

Have you seen this as well or do you know how exactly that should be
worked around?

Cheers

Marcel
