Thanks a lot for all your comments. I think I'll stick with the GPIO
framework for the moment, trying to keep it as simple as possible.

About the generic driver (to allow registering one platform device per
DIO block), I think it won't be possible, because there are shared
regions, such as 0x7d, used by DIO2 and LCD DIO for direction...

Is there a way to share this, or does this mean that this driver should
handle the 3 blocks as it already does?

Thanks,
Vivien
