[PATCH 0/8] ARM: dts: Switch to new DSA binding

[PATCH 0/8] ARM: dts: Switch to new DSA binding

[Florian Fainelli]

Hi all,

This patch series converts the in-tree users to utilize the new (relatively)
DSA binding that was introduced with commit 8c5ad1d6179d ("net: dsa: Document
new binding"). The legacy binding node is kept included, but is marked
disabled.

In about 2-3 releases we may consider removing the old DSA binding entirely
from the kernel.

Thank you!

Hummm, a device tree question. switch@10, reg = <16>. Is there an
implicit understanding that the 10 is hex?

Most (if not all?) unit addresses are hexadecimal, which is why this was
chosen here, but I really don't mind changing that.

And what about using:

I tested this patch on mvebu/dt (I needed to reduce the context to apply
the patch due to the changes made by Russell King on this file). I also
set the status of the old binding to "disable" (instead of "okay").

It seems to work with the limited test did:
ifconfig eth1 up
udhcpc -i lan1
iperf -c mylaptop

(same for lan4)

However is there a way to be sure that the new binding is used?

Yes, that needs fixing, thanks for mentioning that.

The best way is probably to make sure that your switch device appears
parented to the MDIO bus driver under /sys/class/mdio_bus/*mvmdio*.
Alternatively, if you see a message like:

DSA: switch 0 0 parsed

in your dmesg, that would also be indicative of using the new binding
and corresponding code.

Thanks a lot for trying that out!

That makes me think that we should either remove, or use different
values for the version described in net/dsa/dsa.c:

    char dsa_driver_version[] = "0.1";

Today this is absolutely useless and erroneous.

I think it has been useless for over 9 years.

Feel free to remove it.

Do we want to get rid of it, or do we want to have a string version per
DSA implementation? (old vs. new bindings).

I don't like the actual way to distinguish between the two (grep'ing
dmesg as Florian shown). Maybe a pr_info in dsa2.c would be enough to
inform about DSA "v2". What do you guys prefer?

Thanks,

The series looks OK. However I would like to have a reviewed by from
Andrew who know well the mvebu platform and the DSA subsystem.

Also there's few fixes needed for the v2.

Thanks,

Hi Gregory

Yes, i was planning on reviewing, and testing on at least three of
these platforms.

Since this is mvebu/arm-soc and not netdev, i may take a week or so
before i get around to it. netdev is too fast some times.
