My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250114220147.757075-4-ninad@linux.ibm.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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 after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Choose one - suffix or prefix. More popular is suffix.

Best regards,

I was about to say that, but this matches what gpio-hog.yaml defines. 
Why we did both, I don't remember. We could probably eliminate 
'hog-[0-9]+' as that doesn't appear to be used much.

Long term, I want to make all gpio controllers reference a gpio 
controller schema and put the hog stuff there. Then we have the node 
names defined in 1 place.

Only one case:
arch/arm64/boot/dts/nvidia/tegra210-p2894.dtsi:                 hog-0 {

Although there are few "hog" prefixes followed by alphanumeric, so not
matching above pattern.

This. The second part of pattern.

I'll send a patch for dtschema to drop the prefix version.

I am not seeing any error even after upgrading dtschema. Also this mail 
also doesn't show any warning. Is this false negative?

Ok, choosing suffix.

Thanks for the review.

I believe this happens when a prior patch in the series has an error.

Thanks for the response. I have sent a next version.
