I plan to add support for additional cards to this driver that would require the I/O callback functionality of the 8255 module, but the existing callback functions do not have much context to handle this elegantly. The additional cards also have extra DIO features which cannot be handled by the existing "8255" module and that I'd like to support some time in the future. The bottom line is I _could_ continue using the "8255" module for a while with a callback function, but it would turn out to be a very ugly callback function and I'd have to ditch the use of the "8255" module as soon as I added an extra feature to the DIO subdevice.
