  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.
