My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/riscv/thead.yaml: 'thead,vlenb' is not one of ['$id', '$schema', 'title', 'description', 'examples', 'required', 'allOf', 'anyOf', 'oneOf', 'definitions', '$defs', 'additionalProperties', 'dependencies', 'dependentRequired', 'dependentSchemas', 'patternProperties', 'properties', 'not', 'if', 'then', 'else', 'unevaluatedProperties', 'deprecated', 'maintainers', 'select', '$ref']

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240609-xtheadvector-v1-2-3fe591d7f109@rivosinc.com

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.
