The base for a patch series is generally the most recent rc1. 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.

Introduce compatible "linaro,scmi-optee" for SCMI transport channel based on an OP-TEE service invocation. The compatible mandates a channel ID defined with property "linaro,optee-channel-id".
