Documentation/usb/typec.rst tries to explain the actual hierarchy of the devices that the current typec class driver generates, however the "class" does not care about that. Every device will simply have a link added to the class directory (/sys/class/typec/ in our case) regardless of their parent. For example, port0 and its partners: /sys/class/typec/port0 -> ../../devices/<path>/<to>/<your>/<device>/typec/port0 /sys/class/typec/port0-partner -> ../../devices/<path>/<to>/<your>/<device>/typec/port0/port0-partner /sys/class/typec/port0-cable -> ../../devices/<path>/<to>/<your>/<device>/typec/port0/port0-cable /sys/class/typec/port0-plug0 -> ../../devices/<path>/<to>/<your>/<device>/typec/port0/port0-cable/port0-plug0 /sys/class/typec/port0-plug1 -> ../../devices/<path>/<to>/<your>/<device>/typec/port0/port0-cable/port0-plug1 Thanks, -- heikki -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
