Hi all,

This is not exactly new, and was sent before, although back then, I did not
have an user of the pre-declared MDIO board information, but now we do. Note
that I have additional changes queued up to have b53 register platform data for
MIPS bcm47xx and bcm63xx.

Yes I know that we should have the Orion platforms eventually be converted to
Device Tree, but until that happens, I don't want any remaining users of the
old "dsa" platform device (hence the previous DTS submissions for ARM/mvebu)
and, there will be platforms out there that most likely won't never see DT
coming their way (BCM47xx is almost 100% sure, BCM63xx maybe not in a distant
future).

We would probably want the whole series to be merged via David Miller's tree
to simplify things.

Greg, can you Ack/Nack patch 5 since it touched the core LDD?

I've NAKed them for now, you need to describe what you are trying to do
here, as it doesn't make any sense to me at the moment.

For one, this is moving *existing* code from net/dsa/dsa.c part into the
device core for device_find_class() and part into the network device
core for dev_to_net_device(). Patch 8 is where this actually gets used.
See my individual replies for more details.

Even though the existing code is there in net/dsa/dsa.c, at this point,
and for the sake of getting these patches merged via David, I can
probably just keep it where it is (like what patch series v1 did) and
just namespace it with dsa_. Later on, if this is deemed valuable to
other parts of the kernel, I can try to relocate it to the device core,
does that sound acceptable?

Nope!

I really want to try to understand what you all are doing with the
device tree that you feel that blindly walking it actually comes up with
a valid result.

See my other email about wanting to see a tree, we can take it from that
thread to try to consolidate all of these different ones.

And sorry, I know you are just trying to move code around, but this
isn't the first time this has come up, and I think it needs to be
resolved properly.

thanks,
