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/cache/starfive,jh8100-starlink-cache.yaml: $id: Cannot determine base path from $id, relative path/filename doesn't match actual path or filename

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240423072639.143450-3-joshua.yeong@starfivetech.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.

Other than Rob's bot's report, this looks alight to me.

+description:
+  StarFive's JH8100 StarLink Cache Controller manages the L3 cache shared
+  between clusters of CPU cores. The cache driver enables RISC-V non-standard
+  cache management as an alternative to instructions in the RISC-V Zicbom
+  extension.
