Vladimir,
I came across this while looking for the best place to configure cpu port interface mode (ie rgmii id) for the mv88e61xx dsa driver I'm working on. Note that this patch causes port_probe to be called on the cpu port 'before' the master device has been probed. I'm not sure if this is intended or not?
In my case I was looking to configure the cpu port interface mode when the port was probed but I can't do that because it happens before the switch is probed because of some things that need to happen there. Best Regards,

You're past the DM_MDIO probing issues now? Glad to hear that. Probing the DSA CPU port before the master wasn't necessarily the intention, but then again, I'm not sure that there's a strict ordering guarantee between the two that needs to be satisfied?
What do you need exactly? We could probably always reverse the device_probe(master) call with the probing of the CPU port if the ordering turns out to be a real problem. I can regression-test the change on my boards, but I'd like to understand the need you have, maybe even document it so that future changes are aware of it.
