Scratch that. After chatting with dangole, there may be some life in
it, after all. I have an ath25 device (FON2200) and didn't even
remember it.

I am in the process of migrating ath25 to the 5.10 kernel. Initial
build was trivial. But I need to restore the Marvel swconfig driver
that was lost during the initial 5.10 kernel introduction, and
carefully run-time test it.

Does it make sense to directly convert this board to the upstream DSA
driver for the Marvell 88E6060 switch:
https://elixir.bootlin.com/linux/v5.10.72/source/drivers/net/dsa/mv88e6060.c
It looks like our swconfig driver creates a bridge over all ports and
the DSA driver only allows communication between the individual port and
the CPU port.

I do not know how much effort this is and if you have the device for
testing.

I do not think that migration to DSA without DT support will be a
practical step. Let's keep it as is until we are able to run new
kernels with it.


Hi,

You are right as ath25 doesn't use device tree using DSA drivers would be hard. It is probably easier to stay with the swconfig driver.
