I'm not sure that is a valid name for a Signed-off-by. I would expect
something like:

This phy-mode is wrong. There is a long discussion about this, started
from a BMC submitted by IBM. Please wait until Aspeed fix the MAC
driver before adding support for RGMII based ethernet. You are
probably innocent here, apart from failing to sanity check vendor
advise, which happens to be wrong.
https://lore.kernel.org/netdev/20250107162350.1281165-10-ninad@linux.ibm.com/T/
https://lore.kernel.org/linux-arm-kernel/bebbba7b-f86e-4dc4-8253-65d34cb84804@linux.ibm.com/T/
The max-speed parameter should also be unneeded. Unless you have a
real need for it. Does this MAC/PHY combination support higher speeds,
but they are broken for some reason, so you need to avoid them?

Please run scripts/checkpatch.pl and fix reported warnings. After that,
run also 'scripts/checkpatch.pl --strict' and (probably) fix more
warnings. Some warnings can be ignored, especially from --strict run,
but the code here looks like it needs a fix. Feel free to get in touch
if the warning is not clear.

Odd wrapping and alignment. See DTS coding style.

No, look at other DTS. You never start with overrides, this is
completely wrong coding style, completely odd and unacceptable code.

Drop entire bootargs. Use proper stdout-path instead. earlyprintk is
debugging, not mainline-wide use.

No, sorry, you send us crappy downstream code asking us to comment on
exactly the same issues we fixed long time ago.
Drop your entire code and start from scratch from most recently reviewed
upstream code, so you will not duplicate all of the known and fixed
issues.
The exact issue here: Follow DTS coding style for naming.

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

NAK, does not exist.

Where was it disabled?
Please run scripts/checkpatch.pl and fix reported warnings. After that,
run also 'scripts/checkpatch.pl --strict' and (probably) fix more
warnings. Some warnings can be ignored, especially from --strict run,
but the code here looks like it needs a fix. Feel free to get in touch
if the warning is not clear.
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.

Where did you disabled it?
I finished review here, because you have way too many trivial issues
which would be pointed out by tools if you run them.
And you are supposed to run the tools first, before you use community.
