Hi Linus,

Sure but it would be nice to have a dynamic base applied to a controller
(and not to each chip of this controller), and to respect the interval
between the chips (as stated in the controllers datasheets).

This way the assignation would be dynamic and the pin numbers found in
controller datasheet would be meaningful as well.
