We also have DAC and ADC drivers (up to 16 bits @ 64MS/s, via DMA), that would be nice to put in the "right" place - I don't think that drivers/char is the right place, nor drivers/misc - I also don't think that /adc is a descriptive place for DAC or mixed signal front ends (MxFE). 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 think that is the common TLA - at least according to http://en.wikipedia.org/wiki/Data_acquisition ? -Robin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
