I'm OK with this. I'll wait for the v2 and see if I can test these.
The only change I've queued for v2 is adding a "depends on DRM" to
the TYPEC_DP_ALTMODE Kconfig.
And given the discussion about passing lane-info, it might be a while
before we get a v2, so if you want to give this a test run, it is
probably best to just test v1 for now (if you've time).
Note to test this on the GPD win (which you have AFAIK) you will also
need the fusb302 + pi3usb30532 patches I've send out recently, as well as:

I've one Type-C to VGA dongle (without any other functions) where the Type-C
mode negotiation fails. This one does work on a XPS 15 so I need to borrow
some hardware from a friend so that I can capture the USB-PD signals and
see what the Alpine Ridge controller does different compared to the in kernel
stack and fix this. My other 4 dongles work fine, including this "standard"
model:
