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.

Then obvious you must, but that was not the point. Please read writing-bindings document. Compatibles should be SoC specific, not generic. "qspi" is generic. Best regards, Krzysztof

What is this Siflower? That seems like a perfectly adequate description - ${VENDOR} ${FUNCTION} is normal enough and Quad SPI is a well known standard. We don't need a marketing spiel for whatever IP version is currently supported.

Is the company making exactly one and only one Quad SPI? I provided more explanation what is missing further in the quoted email and in follow up email/discussion. Best regards, Krzysztof
