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.

Aren't you missing a break here ?

You should add one here as well. Although not strictly necessary, it would 
help to avoid making the same mistake again.

The rest looks good to me, but I'm not familiar with the hardware, so I'll let 
Valentine have the last word.

    I don't see where this is checked in the driver. Shouldn't we just use gen2?

I'd like to withdraw this patch now.
I intend to post the series patch including this patch at another day.

That would be different. What this patch does is not the same, as using 
GEN2. GEN2 is used in the driver when setting up the hardware for RGB32, 
so, if you would use GEN2 for r8a7795 as well, that code path would be 
used for it too. This patch adds GEN3 without modifying that check, so, if 
you now attempt to use RGB32 with GEN3 / r8a7795 it would issue an 
"invalid" warning and fail. Of course, I have no idea, whether this is the 
intended behaviour, especially since many other chips do seem to support 
RGB32 via that code...

Thanks
