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/aspeed,ast2600-pwm-tach.example.dt.yaml:0:0: /example-0/pwm_tach@1e610000/tach@1: failed to match any schema with compatible: ['aspeed,ast2600-tach']

See https://patchwork.ozlabs.org/patch/1466127

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.
