Isn't "renesas,jpu-gen2" meant as a fallback?

I.e. the DTS should have one of '7790 and '7791, AND the gen2 fallback,
so we can make the driver match against '7790 and '7791 is we find
out about an incompatibility.

Is there a document that clearly states that there is such a thing
as jpu-gen2 in hardware? If not I would prefer not to add a binding for it.
