Yes, I definitely understand that.

I had some time to work on this, I sent you the patches. Except for the
register offset parts, the logic of the driver itself needed no
modifications, so the only "big" change is to pass the register
structure somehow.

Anyway, I just sent to you the patches I had.

Thanks!
