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:
./Documentation/devicetree/bindings/power/power-domain.yaml:72:8: [warning] wrong indentation: expected 6 but found 7 (indentation)

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/power/power-domain.example.dt.yaml:0:0: /example-3/power-controller@...10000/opp-table: failed to match any schema with compatible: ['operating-points-v2']

See https://patchwork.ozlabs.org/patch/1484441

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.
