This patch and "[PATCH 3/3] Add support to M54xx DMA FEC Driver" need to go
through the netdev tree, or collect acks there.

And patch 2/3 never made it to the linux-m68k list. Though I can see
that it made it onto the linux-kernel list.

I would suggest running them through checkpatch, there is a number of
formating and the like issues that need cleaning up.

Also you will want to break up patch 2. It is a bit large to be reviewed
the way it is.

Greg

Hello Geert,

Please, what is the good process to follow as patch 3 depends on patch 1 ?

Submit 1 to m68k tree and wait for it to be pulled on mainline then
push 3 to netdev tree ?

Stany

Hi Greg

I will rework my patches and resend them.

Just make sure to add [email protected] to the CC list, and mention in the
introductory email that you want to collect acks from the netdev maintainer
for patches 1 and 3. After that all 3 patches can go via Greg's m68knommu
tree (for Coldfire).

Thanks!

Gr{oetje,eeting}s,

Actually, IMHO patch 3 does not depend on patch 1, and I even think that
patch 1 is not needed, except to get a message with "BCM5222" instead
of "Generic PHY" in the kernel log.

AFAIK the phy interface is standardized.

I meant patch 3 depends on patch 2 (multi channel dma api)

Hi Stany,

I haven't looked over it in detail, but a few little things anyway.

I would put your signed-off-by line here (with the --- separator).
I would like to see the above text in the commit message.

This should select PHYLIB too, since this driver needs it.

We used to have this on the older FEC driver, but it is all removed
now. I don't think we want this as a config option.
