Hi Andy

[...]

You may do it on stack. Define your cell statically (but not const)
and apply resources just before mfd_add_devices() call.

Ok thanks got it

There are examples in the existing drivers. Intel LPC comes to my mind
and perhaps PMC (Broxton), though latter has too much other stuff
around.

Uh yes I see now in lpc_ich.c (base address is read from PCI config space
and resources are set accordingly).

Cheers
Gab
