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/dma/cirrus,ep9301-dma-m2m.example.dts:24:18: fatal error: dt-bindings/soc/cirrus,ep9301-syscon.h: No such file or directory
make[2]: *** [scripts/Makefile.lib:419: Documentation/devicetree/bindings/dma/cirrus,ep9301-dma-m2m.example.dtb] Error 1

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231122-ep93xx-v5-27-d59a76d5df29@maquefel.me

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.
