tcpciUSB Type-C Port Controller Interface

tcpci* at iic?

The tcpci driver provides support for the USB Type-C Port Controller Interface. It takes care of plug and unplug events on the USB Type-C port and discovers the orientation of the plug so that the USB SuperSpeed pins can be routed correctly. Additionally it enables power on the USB Type-C port when a sink is connected to power attached devices.
