We had lovely hacking session and you can expect some USB-C dock-station support coming to mainline for Snapdragon 660 and 845 soon (maybe 670, if someone will do the testing). 1. phase is dock-stations (no DisplayPort yet). The follow up will be providing supply to usb devices (unpowered USB hubs) and DisplayPort (only for devices with physically wired support). If you're interested in compiling and testing patches, let me know. @alexeymin @setotau @salivo
