Cool.

Would you prefer that, or somewhere else? We have had a drivers/usb/typec directory since v2023.07.0. If you missed it you may also want to check the basic USB Type-C framework that was added there and see how well it fits your driver. > DT binding: I've written the binding as a YAML schema > (st,stusb4500.yaml), matching the Linux dt-schema format and reusing > the common usb-connector.yaml for the connector sub-node. > Where should it go in the Barebox tree? I am unsure why you need a custom schema if there's already one upstream? Anyways, barebox-specific schemas are collected in Documentation/devicetree/bindings/. Upstream bindings are imported to dts/Bindings/ Cheers, Ahmad > > Regards, > Giandomenico Rossi > Amel s.r.l. > -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
