Yes , earlier we had like below settings in our patches,
+       extcon_set_property_capability(info->edev, EXTCON_USB,
+                                      EXTCON_PROP_USB_VBUS);
+       extcon_set_property_capability(info->edev, EXTCON_USB_HOST,
+                                      EXTCON_PROP_USB_VBUS);
+       extcon_set_property_capability(info->edev, EXTCON_USB_HOST,
+                                      EXTCON_PROP_USB_TYPEC_POLARITY);

sure, will add warn message as well.

Thanks!
