What userspace interface do your drivers have? I don't think that there is anything generic available at the moment, other than COMEDI (which is rather outdated as far as I know). > What about /drivers/char/daq or just drivers/daq - drivers for > non-PCI/USB/ISA/PCMCIA Data Acquisition Hardware, D/A and A/D > converters, Analog Front ends, etc. I'd like drivers/daq better, because it doesn't have anything to do with the bus it is connected to; a chipselect bus connectable ADC may be connected to a SoC CS-bus or to a PCI bridge and you want to use the same driver for it.
