The Exynos2200 SoC uses Synopsis eUSB2 PHY. Add a dt-binding schema
for the new driver.

Shouldn't the example have at least all the *required* properties?
Same for patch 2 of this series.

Yeah, this wasn't ever tested.

Device trees were tested with dtbs_check W=1 but I overlooked testing bindings
with dt_bindings_check. Anyways this is rather a small problem, will be fixed
in a v2.

This makes the bindings unreviewable and they will be marked as "changes
requested".

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

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250215122409.162810-2-ivo.ivanov.ivanov1@gmail.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.
