If you do have board designs which somehow managed to introduce
additional dropouts (seems pretty concerning TBH) then I think the best
way to handle that is to add a generic property for it and have that
either added on to or override the requirements of the regulator itself
which should continue to be defined in the driver. That way only boards
with issues need to do anything which will avoid bugs with the property
being omitted in what should be the common case.
