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

yamllint warnings/errors:
./Documentation/devicetree/bindings/misc/qemu,pvpanic-mmio.yaml:33:7: [error] no new line character at the end of file (new-line-at-end-of-file)

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/misc/qemu,pvpanic-mmio.example.dtb: pvpanic@9060000 (qemu,pvpanic-mmio): reg: [[0, 151388160], [0, 2]] is too long
	from schema $id: http://devicetree.org/schemas/misc/qemu,pvpanic-mmio.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260520164846.637522-1-rohanmithari09@gmail.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.

Every guide for kernel development will tell you to run checkpatch.
There are other steps necessary, but some guides are skipping these.
They never skip checkpatch, though.

Best regards,
