Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation


It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
Maybe you need to update your dtschema and yamllint. Don't rely on
distro packages for dtschema and be sure you are using the latest
released dtschema.


> +			reg = <0xFA 0x06>;

Here and in multiple other places - it is always lowercase hex.

Again: please follow DTS coding style.

Odd ordering of properties.

And here totally different. DTS coding style defines one (this is correct).

Totally messed wrapping and alignment/indentation.

and here and the difference in style should trigger your review before
submitting it. Align your code with upstream, not downstream coding style.

[PATCH 3/3] ARM: dts: sunxi: add support for NetCube Systems Kumquat

[Lukas Schmid]

NetCube Systems Kumquat is a board based on the Allwinner V3s SoC,
including:

- 64MB DDR2 included in SoC
- 10/100 Mbps Ethernet
- USB-C DRD
- Audio Codec
- Isolated CAN-FD
- ESP32 over SDIO
- 8MB SPI-NOR Flash for bootloader
- I2C EEPROM for MAC addresses
- SDIO Connector for eMMC or SD-Card
- 8x 12/24V IOs, 4x normally open relays
- DS3232 RTC
- QWIIC connectors for external I2C devices

This seems to be a new version. Please tag the patches with a newer
version. `git format-patch -v2` can do that for you. And please
include a changelog listing the changes between this and the previous
version.

Last, please send the whole series, not just a single patch.

Hi,

Please do not just resend single patches out of a series, and always
update the patch version in the subject - your previous series should have
been v2 already, so that one here would would be:
[PATCH v3 3/3] ARM: dts: sunxi: ....
Also please summarise your changes at an appropriate location, for
individual patches after the "three dashes" (after your Signed-off-by:
below), or for all patches in a cover letter. Git can partly take care of
those things for you:

$ git format-patch -3 -v3 --cover-letter

You will need to "just" fill the generated cover letter file, and send all
of the files again.

In general it's customary to wait for at least a day (ideally more)
before sending a new revision, to allow people from other time zones to
comment.

So in this case here I think you should send a v3 of all patches tomorrow
or on the weekend, that would make it obvious that the other patches are now obsolete.
Also make sure to include Krzysztof's ACKs for patch 1 and 2.

Documentation/process/submitting-patches.rst has some more tips.

Cheers,
Andre

You did not read really the messages we gave you...

1. Read what I wrote in my first reply for v1. I gave detailed
instruction to avoid the exact mistake you now did.

2. Read again Andre's reply.

3. Do not attach (thread) your patchsets to some other threads
(unrelated or older versions). This buries them deep in the mailbox and
might interfere with applying entire sets.

4. Next version, with proper cover letter, is after 24h, so you have
some time to digest the feedback.

Best regards,
Krzysztof

Hi,

Thank you for your feedback, and I sincerely apologize for the mistakes 
in my submission process.

I did read Andre's reply and your feedback on v1, but unfortunately, I 
had already sent the v2 series as a reply before fully understanding all 
the recommendations. I realize now that this was a misstep and caused 
confusion.

I will wait until tomorrow, around 20:00, to send the v3 series. I will 
make sure to include a proper cover letter and ensure that all the 
feedback from v1 and v2 is addressed.

Regarding the v1 feedback, I thought I had incorporated all your 
suggestions. However, after rereading it, I seem to have missed 
something critical. Could you please point out what I might have 
overlooked? I want to make sure I fully understand and correct it in the 
next iteration.

Thank you for your patience and for helping me improve my submission 
process.

Best regards,
Lukas Schmid

Please read my full reply for v1 of this patch. How did you implement
that feedback - long instruction?

I assume by 'long instruction' you mean checking the devicetree using
'make dtbs_check W=1'.

I did run dtbs_check after already applying some of the changes you had
recommended. I just had a look at it's output again, and see now that 
there
is one more issue about 'pinctrl@1c20800: 'gpio-reserved-ranges' does 
not
match any of the regexes'.

Is this what you mean?

If thats the case I'd assume I should add another patch which adds the
'gpio-reserved-ranges' property to the
'devicetree/bindings/pinctrl/allwinner,sun4i-a10-pinctrl.yaml' file.

Best regards,
Lukas

There was nothing like that. Again, we talk about this patch, not other.
You refer now to other patch.

Oh I see now. It's about the Acked-by. I have already added it to the
commit-message of my clone. The V3 will have those two included. I have
read the message from Andre, but unfortunately had already sent the new
patches before I got the mail. I have already applied the tags.

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions
of patchset, under or above your Signed-off-by tag, unless patch changed
significantly (e.g. new properties added to the DT bindings). Tag is
"received", when provided in a message replied to you on the mailing
list. Tools like b4 can help here. However, there's no need to repost
patches *only* to add the tags. The upstream maintainer will do that for
tags received on the version they apply.

Full context and explanation:
https://elixir.bootlin.com/linux/v6.12-rc3/source/Documentation/process/submitting-patches.rst#L577

Best regards,
Krzysztof

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
