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/arm/keystone/ti,sci.yaml: properties:mboxes: 'oneOf' conditional failed, one must be fixed:
	False schema does not allow 2
	[{'description': 'RX thread'}, {'description': 'TX thread'}] is too long
	[{'description': 'RX thread'}, {'description': 'TX thread'}] is too short
	1 was expected
	hint: "minItems" is only needed if less than the "items" list length
	from schema $id: http://devicetree.org/meta-schemas/items.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20251112-k3_syscon_add_boot_mailboxes-v2-1-aebc1e47b391@ti.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.

That's wrong now.

Drop, completely redundant. I don't understand why you added it.
