+description: |
+ 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.
