Returning 0 is no more an error case with MV88E6393 family
which has serdes lane numbers 0, 9 or 10.
So with this change .serdes_get_lane will return lane number
or -errno (-ENODEV or -EOPNOTSUPP).

The Marvell 88E6393X device is a single-chip integration of a 11-port
Ethernet switch with eight integrated Gigabit Ethernet (GbE) transceivers
and three 10-Gigabit interfaces.
This patch adds functionalities specific to mv88e6393x family (88E6393X,
88E6193X and 88E6191X)

Again, what is the value of the comment? 10GBASE-R has a comment
because it is different from the rest, XFI and SFI caused a of
discussion, and it was used wrong. But there does not seem to be
anything special for 5GBASE-R.

return lane
since lane is an errno.

Maybe i'm missing something, but it looks like at this point you can

He can't. That function does not support speed 5000. You can't simply
add it, because it clashes with register value for speed 2500 on
previous switches (Peridot, Topaz).
Amethyst reg val Peridot + Topaz reg val
2500 SPD_1000 | ALT_BIT SPD_10000 | ALT_BIT
5000 SPD_10000 | ALT_BIT not supported
10000 SPD_UNFORCED SPD_UNFORCED
When I sent my proposal for Amethyst I somehow did it, and you
commented [1]:
> This is getting more and more complex. Maybe it is time to refactor it?
And I agree :)

Hi Marek
O.K, as i said, i might be missing something :-)
I think a comment would be nice, pointing this out. Otherwise somebody
might try refactoring it, and make the same mistake!

Returning 0 is no more an error case with MV88E6393 family
which has serdes lane numbers 0, 9 or 10.
So with this change .serdes_get_lane will return lane number
or -errno (-ENODEV or -EOPNOTSUPP).

The Marvell 88E6393X device is a single-chip integration of a 11-port
Ethernet switch with eight integrated Gigabit Ethernet (GbE) transceivers
and three 10-Gigabit interfaces.
This patch adds functionalities specific to mv88e6393x family (88E6393X,
88E6193X and 88E6191X)

Hi Pavana

I don't remember you replying. Why is 5gbase-r special and it needs a
comment, saying the same thing in CAPS LETTERS? What value is there in
the CAPS LETTERS string?

Please don't ignore comments. If you don't understand, please ask. If
you think the comments are wrong, please explain why, so we can
discuss it.

Please add such tags to new versions of the patches. It then makes it
easier for everybody to know the review state of the patches, which
have been reviewed and deemed O.K, and which need more review.

To follow the naming convention, this should really be called mv88e6393x_port_epc_wait_ready

It can be hard to tell in a diff, but the indentation looks wrong
here. 'int lane' should line up with 'struct'.

Maybe here as well?

It should have _serdes_ in the name to follow the naming convention.

There isn't anything special regarding 5gbase-r apart from another supported
speed.
So, I will remove the comment from [PATCH 1 & 2] and keep it similar to other
(1000/2500) speed options.

Returning 0 is no more an error case with MV88E6393 family
which has serdes lane numbers 0, 9 or 10.
So with this change .serdes_get_lane will return lane number
or -errno (-ENODEV or -EOPNOTSUPP).

The Marvell 88E6393X device is a single-chip integration of a 11-port
Ethernet switch with eight integrated Gigabit Ethernet (GbE) transceivers
and three 10-Gigabit interfaces.
This patch adds functionalities specific to mv88e6393x family (88E6393X,
88E6193X and 88E6191X)

This is wrong. IRQ for 5gbase-r and 10gbase-r is enabled differently.
Please look at how I did it in my proposal
https://www.mail-archive.com/netdev@vger.kernel.org/msg347854.html
Please look at the following functions in that patch:
mv88e6393x_serdes_irq_enable_10g()
mv88e6393x_serdes_irq_enable()
mv88e6393x_serdes_irq_status_10g()
irqreturn_t mv88e6393x_serdes_irq_status()
and also at the constants added to serdes.h in that patch
#define MV88E6393X_10G_INT_ENABLE 0x9000
#define MV88E6393X_10G_INT_LINK_CHANGE BIT(2)
#define MV88E6393X_10G_INT_STATUS 0x9001

I also sent a reply patch with subject
"patch fixing mv88e6393x SERDES IRQ for Pavana's series"
it contains the changes necessary to your series. Please look at that.
You can apply it to your commit via
patch -p1 <patch_from_marek.patch
git commit --amend drivers/net/dsa/mv88e6xxx/{chip.c,serdes.c,serdes.h}
