What about renaming RCAR_H2 to RCAR_GEN2 instead, and using RCAR_GEN2 for both
r8a7790 and r8a7791 (but keeping the "r8a7790-vin" and "r8a7791-vin" device
IDs as you've done below) ? They're identical so far (at least from what's
implemented in the driver, you might be aware of features specific to the H2
or M2 that are not yet supported but will be implemented in the near future).
Yes, the driver won't see any difference at this point.
The h/w (at least the input data formats supported) seems a bit different
though.
The M2 variant doesn't seem to support 4-bit data (AOT H2).
I'm not aware or any M2 or H2 specific features that need to be implemented in
the near future.
I've preferred to keep them separate just in case.
I wouldn't mind to use the same (GEN2) id for both but we may need to split
them in the future.
