My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/mtd/partitions/binman/atf-bl31.example.dtb: /example-0/binman/partition@0: failed to match any schema with compatible: ['binman,entry']
Documentation/devicetree/bindings/mtd/partitions/binman/entry.example.dtb: /example-0/binman/partition@0: failed to match any schema with compatible: ['binman,entry']
Documentation/devicetree/bindings/mtd/partitions/binman/entry.example.dtb: /example-0/binman/partition@100000: failed to match any schema with compatible: ['binman,entry']

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230922193417.1697379-1-sjg@xxxxxxxxxxxx

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.
