[PATCH 0/3] extcon: Add Type-C Virtual PD

[Jagan Teki]

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
of operations as separate protocol connectors like design
Display Port from on-chip USB3 controller. So accessing
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.

This series support this Type-C Virtual PD and enable the
same in ROCK Pi 4C SBC.

Any inputs?
Jagan.
