 734          *   two Type C connectors and want to be able to achieve 4 lanes of DP.
 735          * - When you configure a Type C port for 4 lanes of DP you lose USB3.
 736          * - In order to make everything work, the native Type C port is always
 737          *   configured as 4-lanes DP so it's always available.
 738          * - The extra USB3 port on SDM845 goes to a USB 3 hub which is then
 739          *   sent to the two Type C connectors.
 740          * - The extra USB2 lines from the native Type C port are always
 741          *   setup as "peripheral" so that we can mux them over to one connector

 746          * ways to some potential benefit for static configurations (you could
 747          * achieve extra USB2 bandwidth by using two different ports for the
