Hi,

Since we now have an implementation for an actual alternate mode (DisplayPort),
I guess there is no reason to send another RFC. This series is the same as the
last RFC proposal [1] with only minor changes. There were only a few comments.

[1] https://lkml.org/lkml/2018/6/8/225

I've tested these with a platform that has fusb302, and also with UCSI
platforms. The UCSI driver will need separate support for alternate modes that
I'm not including to this series. I'm still working on it. I've used various
DisplayPort to Type-C adapters for testing, both DisplayPort receptacles and
connectors.

I've tested that this series does not cause any regression wrt
PD or susperspeed host and gadget mode on a device with a fusb302 controller:
