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/mfd/mediatek,mt6357.yaml: Unable to find schema file matching $id: http://devicetree.org/schemas/rtc/mediatek,mt6397-rtc.yaml
Error: Documentation/devicetree/bindings/mfd/mediatek,mt6357.example.dts:26.35-36 syntax error
FATAL ERROR: Unable to parse input tree

make: *** [Makefile:1492: dt_binding_check] Error 2

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.
