What I mean is that if we want to specify that any pin of those drivers
are locked down we would make npins = 0.

But as this is a system configuration thing this information would
preferably be injected in runtime (like you do), but the
soc_data->groups arrays are currently all const (see e.g.
msm8x74_groups), so we can't change npins in runtime.


But I think this is fine for now.
