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.

We do have a document that describes the "JPEG Processing Unit (JPU)",
as found in the following members of the "Second Generation R-Car Series
Products": "R-Car H2", "R-Car M2-W", "R-Car M2-N", and "R-Car V2H".

Oh, that is nice :)

From my point of view that ticks a lot of boxes.
But I wonder if we can come up with a better name than jpu,-gen2.

"jpu-rcar-gen2"?
