This gets expanded to 'maxItems: 2'. Is that what you want? If not,
maxItems should be explicit.

Hi Rob,
Thank you very much for the review!

Yes, 'maxItems: 2' is what I want but I can also add 'maxItems: 2' in v3 to be
explicit/more clear about it.

I will fix in v3.
Best regards,

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.

I will wait a bit for other comments and I will fix in v3. Best regards, Andrei
