+description: |
+ USB Type-C protocol supports various modes of operations includes PD,
+ USB3, and Altmode. If the platform design supports a Type-C connector
+ then configuring these modes can be done via enumeration.
+
+ However, there are some platforms that design these modes as separate
+ protocol connectors like design Display Port from on-chip USB3 controller.
+ So we can access Type-C Altmode Display Port via onboard Display Port
+ connector instead of a Type-C connector. These kinds of platforms require
+ an explicit extcon driver in order to handle Power Delivery and
+ Port Detection.
