Hi, This is the fourth (and hopefully last RFC) of my proposal for more complete alternate mode support. In this version the main difference compared to the previous versions is the displayport alt mode driver. For those who have no idea what is this about, the idea is to add a bus type for the USB-C alternate modes. All alternate modes, for example DisplayPort, require specific communication, so we will need separate driver for every alternate mode. For more details please read the cover letter of the previous version here: https://lkml.org/lkml/2018/5/11/323 It took some time for me to get permission to publish the displayport alt mode driver. Sorry for the delay. I was actually hoping that I could include changes also to the drm subsystem already now, but it ended up being more complicated than I first though, and I quite simply don't have time for that, so let's just start with these.
