+ * subnodes of ports identified with a reg property, themselves in a
+ * "ports" container.

+ * The device is probed to activate it ready for use.
+ *
+ * @class_id: uclass ID to look up
+ * @dev: Device to start from
+ * @port_idx: Index of the port to follow, -1 if there is a single 'port'
+ *            node without reg.
+ * @ep_idx: Index of the endpoint to follow, -1 if there is a single 'endpoint'
+ *          node without reg.
+ * @target: Returns pointer to the first device matching the expected uclass.
+ * Return: 0 if OK, -ve on error
