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:
Error: Documentation/devicetree/bindings/dma/renesas,rz-dmac.example.dts:49.30-31 syntax error
FATAL ERROR: Unable to parse input tree
make[1]: *** [scripts/Makefile.lib:380: Documentation/devicetree/bindings/dma/renesas,rz-dmac.example.dt.yaml] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:1418: dt_binding_check] Error 2
\ndoc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1506873

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.

The dependency patch for the bot error is present on 5.14-rc2 but not on 5.14-rc1.
