V1 -> V2:
  - Added copyright header and data sheet links
  - Removed non-existent property
  - Sorted alphabetically
  - Removed errant whitespace
  - Moved status to the end of each node
  - Removed pinctrl-names property from leds (indicated by CHECK_DTBS)
  - Removed delays from gmac with internal delay

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:
./Documentation/devicetree/bindings/arm/rockchip.yaml:846:13: [warning] wrong indentation: expected 14 but found 12 (indentation)

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250515220034.393303-1-joseph.kogut@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

[PATCH v3 0/3] Add Radxa CM5 module and IO board dts

[Joseph Kogut]

This patch series adds initial device tree support for the Radxa CM5 SoM
and accompanying IO board.

V2 -> V3:
  - Addressed YAML syntax error in dt binding (per Rob)
  - Fixed whitespace issue in dts reported by checkpatch.pl
  - Split base SoM and carrier board into separate patches
  - Added further details about the SoM and carrier to the commit
    messages

V1 -> V2:
  - Added copyright header and data sheet links
  - Removed non-existent property
  - Sorted alphabetically
  - Removed errant whitespace
  - Moved status to the end of each node
  - Removed pinctrl-names property from leds (indicated by CHECK_DTBS)
  - Removed delays from gmac with internal delay

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.

This is an automated instruction, just in case, because many review
tags are being ignored. If you know the process, just skip it entirely
(please do not feel offended by me posting it here - no bad intentions
intended, no patronizing, I just want to avoid wasted efforts). 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.

Re: [PATCH v3 1/3] dt-bindings: arm: rockchip: Add Radxa CM5 IO board

[Joseph Kogut]

I've reviewed the man page for git-send-email. If I'm understanding
correctly, I should only thread the *cover letter* of the patch series
when submitting a new version. That didn't work for me here because I
didn't initially include a cover letter, then tried to thread the
first patch in the series. I see now how that would be disruptive.

Thanks for the review, and the help with threading, Krzysztof. Parts
of the mailing list etiquette are still new to me.

Best,
Joseph

You should not thread manually anything. b4 does it for you. If you want
to use git-send-email, then you also don't care:

git format-patch -v3 -3 HEAD
git send-email <whatever-to-and-cc-arguments> v3*

That's it. No manual threading.

Krzysztof

I wasn't aware of b4, it looks like a great tool for this workflow.
Thanks again for your help, I'll give it a try.

Please explain the sorting rule used for this file. You must have known 
the sorting rule; otherwise, how can you be sure this patch is correct?

Huh? I don't have a clue about sorting rule but if you mock my review
let's make it different:

I have Joseph's permission to post my patch.

Furthermore, this is not the first time, to my knowledge, that someone 
else has posted another patch for the same board. (See below)
