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.

Except that this was never tested... wild-cards are generally not allowed.

I realized I made a mistake when using the "make dt_binding_check" 
command, which led to some errors in this dt_binding. I have now 
addressed all of them, but I'm not sure I understand your comment.

I don't see any wildcards in the YAML file. Could you please provide 
more details on what you expect?

Best regards,
Thomas

What is "xx"? Sounds like wildcard. I do not see such SoC compatible.

The point of cv18xx is to have a single compatible for all SoCs of the 
cv18xx series from Sophgo (cv1800b, cv1812h but also sg2000 and sg2002). 
I used that as a reflection of the cv18xx.dtsi used for all those SoCs.

Should I create multiple compatible for all the SoCs of a same brand ?

You can use cv1800-xxx as a base compatible. 
Add new compatible when other SoCs have different features.

+      SARADC will use the presence of this clock to determine if the controller
+      needs to be explicitly clocked by it (Active domain) or if it is part of
+      the No-Die Domain, along with the RTC, which does not require explicit
+      clocking.
