a=openpgp; fpr=89EC3D058446217450F22848169AB7B1A4CFF8AE In the Type-C graph, a retimer is usually in between the USB-C connector and the USB3/DP combo PHY, and this PHY also requires the USB-C mode events to properly set-up the SuperSpeed Lanes functions to setup USB3-only, USB3 + DP Altmode or DP Altmode only on the 4 lanes. Update the nb7vpq904m & ptn36502 retimers to get an optional type-c mux on the next endpoint, and broadcast the received mode to it. This makes it possible to support 4-lanes DP altmode on Qualcomm platforms.
