[v2,15/16] dt-bindings: soc: socionext: Add UniPhier DWC3 USB glue layer
Commit Message
Add DT binding schema for components belonging to the platform-specific
DWC3 USB glue layer implemented in UniPhier SoCs.
This USB glue layer works as a sideband logic for the host controller,
including core reset, vbus control, PHYs, and some signals to the
controller.

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20221207055405.30940-16-hayashi.kunihiko@socionext.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.

You need to fix
Documentation/devicetree/bindings/phy/socionext,uniphier-usb3hs-phy.yaml
example. I propose to drop usb-glue@65b00000 from that file. It's not
relevant to that example.
Best regards,
Krzysztof

I already fixed usb3-phy example in PATCH 6/16, however, it's better
to drop the parent node from the example not to avoid the effect of the changes.
