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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/firmware/qcom,scm.example.dtb: sram@14680000 (qcom,kaanapali-imem): 'minidump-config@1c' does not match any of the regexes: '^([a-z0-9]+-)*sram(-section)?@[a-f0-9]+$', '^pinctrl-[0-9]+$'

See https://patchwork.kernel.org/project/devicetree/patch/20260507080727.3227367-2-mukesh.ojha@oss.qualcomm.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.
