+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.
