The RichTek RT1711H and RT1719 chips do have a vbus pin that is used for attach/detach detection (respectively, pin A1 and 11): allow a vbus-supply phandle for that.

The RT1711H is a USB Type-C controller that complies with the latest
|
|
USB Type-C and PD standards. It does the USB Type-C detection including attach
|
|
and orientation. It integrates the physical layer of the USB BMC power
|
|
delivery protocol to allow up to 100W of power. The BMC PD block enables full
|
|
support for alternative interfaces of the Type-C specification.
