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