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.

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. Thank you, --- Best Regards Kunihiko Hayashi

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.
