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/spi/rockchip-sfc.yaml:45:5: [warning] wrong indentation: expected 2 but found 4 (indentation)
dtschema/dtc warnings/errors:
\ndoc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/patch/1489897
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.
