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:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/net/can/microchip,mpfs-can.yaml: properties:clocks: {'maxItems': 2, 'items': [{'description': 'AHB peripheral clock'}, {'description': 'CAN bus clock'}]} should not be valid under {'required': ['maxItems']}
hint: "maxItems" is not needed with an "items" list
from schema $id: http://devicetree.org/meta-schemas/items.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231208-palpitate-passable-c79bacf2036c@spud

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.
