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

yamllint warnings/errors:
./Documentation/devicetree/bindings/display/sprd/sprd,sharkl3-dpu.yaml:38:9: [warning] wrong indentation: expected 10 but found 8 (indentation)
./Documentation/devicetree/bindings/display/sprd/sprd,sharkl3-dpu.yaml:41:9: [warning] wrong indentation: expected 10 but found 8 (indentation)

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250719-ums9230-drm-v1-1-e4344a05eb3d@abscue.de

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.
