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:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/crypto/intel,ixp4xx-crypto.example.dt.yaml: npe@c8006000: 'crypto' does not match any of the regexes: 'pinctrl-[0-9]+'
From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/firmware/intel,ixp4xx-network-processing-engine.yaml
See https://patchwork.ozlabs.org/patch/1476741
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 parent schema needs to define 'crypto' and have a ref to this
schema. I'd put the example there rather than piecemeal.

A bit redundant to have a phandle to the parent.
