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/mmc/hisilicon,hi3798cv200-dw-mshc.yaml: properties:clock-names:items: 'oneOf' conditional failed, one must be fixed:
	[{'const': 'ciu'}, {'const': 'biu'}, {'const': 'ciu-sample', 'description': 'card output sampling phase clock'}, {'const': 'ciu-drive', 'description': 'card input driving phase clock'}] is not of type 'object'
	Additional properties are not allowed ('description' was unexpected)
	from schema $id: http://devicetree.org/meta-schemas/string-array.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240216-b4-mmc-hi3798mv200-v2-3-010d63e6a1d5@outlook.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.

-* Hisilicon Hi3798CV200 specific extensions to the Synopsys Designware Mobile
-  Storage Host Controller
-
-Read synopsys-dw-mshc.txt for more details
-
-The Synopsys designware mobile storage host controller is used to interface
-a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
-differences between the core Synopsys dw mshc controller properties described
-by synopsys-dw-mshc.txt and the properties used by the Hisilicon Hi3798CV200
-specific extensions to the Synopsys Designware Mobile Storage Host Controller.
-
-Required Properties:
-- compatible: Should contain "hisilicon,hi3798cv200-dw-mshc".
-- clocks: A list of phandle + clock-specifier pairs for the clocks listed
-  in clock-names.
-- clock-names: Should contain the following:
-	"ciu" - The ciu clock described in synopsys-dw-mshc.txt.
-	"biu" - The biu clock described in synopsys-dw-mshc.txt.
-	"ciu-sample" - Hi3798CV200 extended phase clock for ciu sampling.
-	"ciu-drive"  - Hi3798CV200 extended phase clock for ciu driving.
-
-Example:
-
-	emmc: mmc@9830000 {
-		compatible = "hisilicon,hi3798cv200-dw-mshc";
-		reg = <0x9830000 0x10000>;
