Consider if they are expected or the schema is incorrect. These may not be new warnings. Note that it is not yet a requirement to have 0 warnings for dtbs_check. This will change in the future.

This adds bindings for features in the USB glue block. They allow setting polarity of PWR and OC as well as disabling port power control. Also permanently attached can be annotated as well. Additional IO address and clock are needed.
