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/dt-review-ci/linux/Documentation/devicetree/bindings/leds/register-bit-led.example.dtb: syscon@...00000: compatible: 'oneOf' conditional failed, one must be fixed:
	['arm,realview-pb1176-syscon', 'syscon'] is too short
	'arm,realview-pb1176-syscon' is not one of ['arm,integrator-ap-syscon', 'arm,integrator-cp-syscon', 'arm,integrator-sp-syscon', 'arm,im-pd1-syscon']
	'arm,realview-pb1176-syscon' is not one of ['arm,realview-eb11mp-revb-syscon', 'arm,realview-eb11mp-revc-syscon']
	'arm,realview-eb-syscon' was expected
	from schema $id: http://devicetree.org/schemas/mfd/arm,dev-platforms-syscon.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230915201520.4179115-1-robh@kernel.org

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.
