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.
