VAR-SOM-NANO with a NXP MX8MN nano CPU.

Eh, now it does not match your DTS.

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).

Best regards,
Krzysztof

Hi,
for the millionth time, make dtbs_check stopped working for me:

Traceback (most recent call last):
  File "/usr/local/bin/dt-doc-validate", line 64, in <module>
    ret |= check_doc(f)
           ^^^^^^^^^^^^
  File "/usr/local/bin/dt-doc-validate", line 32, in check_doc
    for error in sorted(dtsch.iter_errors(), key=lambda e: e.linecol):
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/dist-packages/dtschema/schema.py",
line 125, in iter_errors self.annotate_error(scherr, meta_schema,
scherr.schema_path) File
"/usr/local/lib/python3.11/dist-packages/dtschema/schema.py", line 104,
in annotate_error schema = schema[p] ~~~~~~^^^

After a few hours of searching and troubleshooting, I am unable to fix
the problem.

But even with this error, I can still see the warnings, which I
discarded as garbage initally because of that Traceback error.

I now see the problem, and I moved "rve,rve-gateway" to the proper
section, in "Variscite VAR-SOM-MX8MN based boards".

After the move, I still have an error, but now I understand that I must
slightly convert the "Variscite VAR-SOM-MX8MN based boards" to support
more than one board like this:

       - description: Variscite VAR-SOM-MX8MN based boards
         items:
-          - const: variscite,var-som-mx8mn-symphony
+          - enum:
+              - rve,rve-gateway # i.MX8MN RVE Gateway Board
+              - variscite,var-som-mx8mn-symphony
           - const: variscite,var-som-mx8mn
           - const: fsl,imx8mn

With these changes, everything looks good now.

I Will send a V4 with these changes.

Thank you,
Hugo.
