I haven't looked at the v2 but they seemed to be doing an alright job at getting things upstreamed with the v1. the only thing i remember seeing that wasn't very good in that regard was the neural net stuff that they had and that seemed more from just issues getting the hardware working than any nda or lack of desire to do it. I'd hope that the v2 is similarly worked through even if it needs some non-upstream patches at the start just because it's new hardware and it takes time.

It seems like many SoCs (also in ARM space) advertise '2 TOPS' or however many TOPS neural processors integrated in the silicon... but the actual number of SoCs where those coprocessors can be used in Linux seems to be very low.

yea it's a shame that it seems to be the normal state of things still. Based on the fact that so many of them have the exact same specs I think it's probably all the same (or only a few) vendors that make that part of the silicon/IP and everyone is just copying it without ever planning much around the support.
