I think TBH before we see a next version, there needs to be a conclusive 
argument on why a new driver - instead of an update to the existing 
venus - is the way to go.

We have an ongoing corpus of working code that people use. The attempt 
to at least _try_ to integrate 8550 and beyond to upstream venus should 
be made.

If it fails, then we can discuss a branched driver.

Its not up to me but, that's certainly my honest and unvarnished input.

Instead of investing time in V2 - please invest time in upstream venus 
or make the technical argument conclusively _prior_ to V2 as to why V2 
and beyond is the "only" way forward for 8550 and beyond.
