If your target is just the iwg23s, this is indeed fine.
However, you may have customers who want to use this SoC in their own products,
and thus aren't limited to the pins available on iwg23s.
Including this support upstream makes their life easier. While not everything
can be tested, it will at least have received some review.

Anyway, I'll queue this series in sh-pfc-for-v4.20.

Gr{oetje,eeting}s,

The iwg23s is a very small Raspberry Pi like SBC, there isn't much on it, 
therefore we can't test all of the interfaces we would like to test.
The plan is to start supporting what we can easily test/access, for everything 
else we would like to wait and see, maybe at a later stage?

Thanks,
Fab

Thanks for your patch!

Any specific reason you added I2C4 only, and not the other I2C instances?
Usually we add all of them in one run.
