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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/mmc/bst,dwcmshc-sdhci.example.dtb: /example-0/bus/mmc at 22200000: failed to match any schema with compatible: ['bst,c1200-dwcmshc-sdhci']

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250923-v4-patch-final-v1-4-2283ad7cbf88@thundersoft.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.
