There are a couple comedi drivers for 8255 based I/O boards. They are all virtually identical: adl_pci7296.c supports 3 ADLink board types cb_pcidio.c supports 3 ComputerBoards (MeasurementComputing) board types ni_pcidio.c supports 7 National Instruments board types The ni_pcidio driver is a bit goofy since is also handles a couple dio boards that are not 8255 based. It also has the mite stuff which I still need to wrap my head around... The support for these boards could all be merged into the adl_pci7296 driver pretty easily. Should I do this? This would completely remove the cb_pcidio driver and make the ni_pcidio driver a lot cleaner.
