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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/i2c/i2c-mux-reg.example.dtb: /example-0/i2c-mux@6028/i2c@0/clock-generator@70: failed to match any schema with compatible: ['silabs,si5338']

doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260607-i2c-mux-reg-base-bus-num-v1-1-f193b5a8fedc@nexthop.ai

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.
