This series brings a variety of fixes and enhancements for mtk_eth_soc,
adds support for the MT7981 SoC and facilitates sharing the SGMII PCS
code between mtk_eth_soc and mt7530.
Also prepare support for MT7988 which has been done while net-next was
closed.
Note that this series depends on commit 697c3892d825
("regmap: apply reg_base and reg_downshift for single register ops") to
not break mt7530 pcs register access.
For SGMII and 1000Base-X mode to work well it also depends on commit
193250ace270 ("net: ethernet: mtk_eth_soc: fix RX data corruption issue")
which has already been merged via the net tree.
The whole series has been tested on MT7622+MT7531 (BPi-R64),
MT7623+MT7530 (BPi-R2), MT7981+GPY211 (GL.iNet GL-MT3000) and
MT7986+MT7531 (BPi-R3). On the BananaPi R3 a variete of SFP modules
have been tested, all of them (some SGMII with PHY, others 2500Base-X
or 1000Base-X without PHY) are working well now, however, some of them
need manually disabling of autonegotiation for the link to come up.
Changes since v12:
* remove patches "fixing" ????Base-X modes. Turns out the cause are
buggy SFP modules for which we will need to introduce quirks rather
than trying to address this in the Ethernet driver.
Changes since v11:
* remove patch "net: ethernet: mtk_eth_soc: fix RX data corruption issue"
as it has already been merged via net tree
* add commits fixing 1000Base-X and 2500Base-X modes after phylink_pcs
conversion
* completely remove mtk_sgmii.c as only about 20 lines were left in that
file
* Add commits from Lorenzo for MT7988 as requested by him
Changes since v10:
* improve mediatek,mt7981-eth dt-bindings
* use regmap_set_bits instead of regmap_update_bits where possible
* completely remove mtk_sgmii.c
* no need to keep struct mtk_sgmii either as it had only a single
element
Changes since v9:
* fix path in mediatek,sgmiisys dt-binding
Changes since v8:
* move mediatek,sgmiisys dt-bindings to correct net/pcs folder
* rebase on top of net-next/main so series applies cleanly again
Changes since v7:
* move mediatek,sgmiisys.yaml to more appropriate folder
* don't include <linux/phylink.h> twice in PCS driver, sort includes
Changes since v6:
* label MAC MCR bit 12 in 08/12, MediaTek replied explaining its function
Changes since v5:
* drop dev pointer also from struct mtk_sgmii, pass it as function
parameter instead
* address comments left for dt-bindings
* minor improvements to commit messages
Changes since v4:
* remove unused dev pointer in struct pcs_mtk_lynxi
* squash link timer check into correct follow-up patch
Changes since v3:
* remove unused #define's
* use BMCR_* instead of #define'ing our own constants
* return before changing registers in case of invalid link timer
Changes since v2:
* improve dt-bindings, convert sgmisys bindings to dt-schema yaml
* fix typo
Changes since v1:
* apply reverse xmas tree everywhere
* improve commit descriptions
* add dt binding documentation
* various small changes addressing all comments received for v1

2.39.2
The MediaTek MT7981 SoC comes with two 1G/2.5G SGMII ports, just like
MT7986.
In addition MT7981 is equipped with a built-in 1000Base-T PHY which can
be used with GMAC1.
As many MT7981 boards make use of inverting SGMII signal polarity, add
new device-tree attribute 'mediatek,pn_swap' to support them.

2.39.2
Convert mediatek,sgmiiisys bindings to DT schema format.
Add maintainer Matthias Brugger, no maintainers were listed in the
original documentation.
As this node is also referenced by the Ethernet controller and used
as SGMII PCS add this fact to the description.
Move the file to Documentation/devicetree/bindings/pcs/ which seems more
appropriate given that the great majority of registers are related to
SGMII PCS functionality and only one register represents clock bits.

2.39.2
The SGMII core found in several MediaTek SoCs is identical to what can
also be found in MediaTek's MT7531 Ethernet switch IC.
As this has not always been clear, both drivers developed different
implementations to deal with the PCS.
Recently Alexander Couzens pointed out this fact which lead to the
development of this shared driver.
Add a dedicated driver, mostly by copying the code now found in the
Ethernet driver. The now redundant code will be removed by a follow-up
commit.

2.39.2
Implement regmap access wrappers, for now only to be used by the
pcs-mtk driver.
Make use of external PCS driver and drop the reduntant implementation
in mt7530.c.
As a nice side effect the SGMII registers can now also more easily be
inspected for debugging via /sys/kernel/debug/regmap.

2.39.2
From: Lorenzo Bianconi <[email protected]>
Introduce MTK_NETSYS_V1 bit in the device capabilities for
MT7621/MT7622/MT7623/MT7628/MT7629 SoCs.
Use !MTK_NETSYS_V1 instead of MTK_NETSYS_V2 in the driver codebase.
This is a preliminary patch to introduce support for MT7988 SoC.

The netdev review queue is too long for me to comprehend, since the
discussion is still ongoing on v12 (even tho seemingly tangential)
I'll drop this, please repost once conclusion is reached.

When posting v14 please do us a favor and withhold this patch.
It looks like the series doesn't need it and the limit on patches
in one series is 15.

These new functions can be used for both switches, mt7530 and mt7531,
correct? If so, I believe they are supposed to be called mt753x since
88bdef8be9f6 ("net: dsa: mt7530: Extend device data ready for adding a
new hardware").
mt753x: functions that can be used for mt7530 and mt7531 switches.
mt7530: functions specific to mt7530 switch.
mt7531: functions specific to mt7531 switch.

In theory, yes, they could be used on all switch ICs supported by the
mt7530.c driver. In practise they are used on MT7531 only because MT7530
and MT7621 don't have any SGMII/SerDes ports, but only MT7531 does.

Good catch, so mt7530_* is for sure not accurate. I used that naming
due to existing function names mt7530_read, mt7530_write and mt7530_rmw.
Given the situation I've explained above I think that mt753x_* would
be the best and I will change that for v14.
Thank you for reviewing!

I was going to send a mail to netdev mailing list to ask for opinions
whether we should rename the mt7530 DSA driver to mt753x and rename
these functions you mentioned to mt753x so it's crystal clear what code
is for what hardware. Now that we glossed over it here, I guess I can
ask it here instead.

My 2 cents - make your first 100 useful commits on this driver, which at
the very least produce a change in the compiled output, and then go on a
renaming spree as much as you want.

Look, I don't ask for renaming just for the sake of renaming things. I
see a benefit which would make things clearer.
If you rather mean to, know the driver very well, by saying do 100
useful commits on the driver beforehand, that makes sense. But I think
I'm capable of managing this. I've got the time and energy.

I'm absolutely sure that you're capable of renaming mt7530 to mt753x,
that's outside the question. That change can be made without even paying
too much attention to the code, which is exactly the problem. If the
proposal is to touch mt7530_read(), mt7530_write(), mt7530_rmw()
(which it seems to be), then that's pretty much the entire driver.
Sorry for being skeptical by default, but generally such refactoring is
done by people who have the commitment to stay around when shit hits the
fan. Think of it as minimizing the time wasted by others due to that
refactoring. That could be time spent by reviewers looking at the code
being changed while trying to identify latent bugs; could be time spent
by someone who fixes a bug that doesn't backport all the way to stable
kernels because it conflicts with the refactoring. Ideally, after a
large refactoring, you would be sufficiently active to find and fix bugs
before others do, and have an eye for problematic code. Respectfully,
you still need to prove all these things. It also helps a lot if you
build a working relationship with the driver maintainers, or if you gain
their trust and become a maintainer yourself. Otherwise, more work will
just fall on the shoulders of fallback maintainers who don't have the
hardware. If there is a self-sustaining development community and they
take care of everything, I really have zero problems with large
refactoring done even by newbies. But the mt7530 maintainers have gone
pretty silent as of late, and I, as a fallback maintainer with no
hardware, have had to send 2 bug fixes to the mt7530 and 1 to the
mtk_eth_soc driver in the past month, to address the reports. Give me a
reason not to refuse more potential work :)
It's great that you have the time and energy, but with the symbolic 100
commits I just meant: start somewhere else within the driver, build the
experience, the knowledge of the development process and the appreciation
for the existing code structure.

That's an under-statement, and not just the DSA driver, but the
ethernet driver too. It's been years trying to get the attention
of anyone to sort out the pre-March 2020 crud in this driver, and
no one seems to care, and none of the alleged maintainers bother
replying.
I don't believe anyone who claims to be a maintainer for either the
DSA or Ethernet driver has commented on any of my patches or provided
any review.
In my mind, these drivers do not have maintainers.
What I have to resort to is spotting potential victims^wtesters on
the mailing lists to try stuff out for me - which is really not
how this should work.
It seems to me that this is the old "chuck code over the wall into
mainline, then do a runner" approach to kernel maintenance.
So, honestly, the sooner these drivers get proper maintainers, the
better - and if someone wants to step up to do that amongst those
who are involved in the current work, I'm all for that - it would
be a hell of a lot better than the current situation.

Now, I can find bugs if it's something that would appear on a daily use
of the hardware, like those bugfixes you mentioned which I reported to
you. I'm not confident in fixing them myself (yet!) due to my very
slowly learning C but I'm willing to stick around for years to come so
who knows what happens in a few years. I already do keep an eye on a
very small problematic code at least.
I can be around as a maintainer to help backporting bugfixes that
wouldn't apply cleanly due to my refactoring. So I don't add more
workload to fallback maintainers like yourself. But that's all I can
promise to maintain for now, not because of availability but experience,
or rather the lack thereof.
