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/arm/apple/apple,pmgr.example.dts:30.40-35.15: ERROR (duplicate_node_names): /example-0/soc/power-management@...700000: Duplicate node name
ERROR: Input tree has errors, aborting (use -f to force output)
make[1]: *** [scripts/Makefile.lib:385: Documentation/devicetree/bindings/arm/apple/apple,pmgr.example.dt.yaml] Error 2

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1536742

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.
