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/media/i2c/sony,imx519.yaml: $id: Cannot determine base path from $id, relative path/filename doesn't match actual path or filename
$id: http://devicetree.org/schemas/media/i2c/imx519.yaml

doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230727154108.308320-2-umang.jain@ideasonboard.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.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.

A nit, subject: drop second/last, redundant "DT bindings". The
"dt-bindings" prefix is already stating that these are bindings.

That's not how this is done. Open existing bindings, e.g. imx219, 258 or
any other and look. Please, do not write patches entirely different than
all other drivers/bindings. There is a reason why some things work but
other don't

drop the label imx519.
