Ditch the device_type.

As I answered then, it's just the way the hardware is. I didn't design it. :-P

No, it's used by the bootwrapper. I'll get rid of it if you want to write a find_node_by_compatible() function. :-)

I obviously missed when you answered this before, I was hoping for some more detail.
I mean, obviously the MDIO bus is accessed via some of the board-control registers. What I'm questioning is whether it makes sense to have a distinct node to represent the mdio bus, or whether the phys should just hang straight of the bcsr node.

Well, now that libfdt is merged, there is one :-p.

Ah, I see. I think it does make sense, because it's a bus; if there were another bus-like thing on the bcsr, there'd be conflicts over what the children mean.

OK, it just needs exporting via ops. I'll put it on my to-do list, but I don't think it should hold up board support patches.
