Hi, This is fourth version of this series. There was one bug in patch 2/10 that Hans noticed. It should be fixed now. The commit message from v3: These patches will introduce a few improvements to the USB Type-C support on Intel CHT platform. In this series I'm preparing Intel CHT mux handling for DisplayPort Alt Mode support, but please note that, after these patches the DisplayPort alternate mode will still not work out of the box on CHT platform. Changes to the fusb302.c, and possibly tcpm.c are still needed. This version will only fix the issue Hans pointed out in v2. Instead of replacing the connection that assigned the mux to the USB Type-C port with a connection that assigns the mux to the alternate mode device, we keep all the existing connections and add a new one for the alternate mode device. That way USB3 devices continue to be enumerated as USB3 devices instead of USB2 devices.
