    iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8 · 28e5d3bb
    William Breathitt Gray authored
    The ACCES 104-QUAD-8 is a general purpose quadrature encoder
    counter/interface board. The 104-QUAD-8 is capable of monitoring the
    outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit
    dual-axis quadrature counter chips. Core functions handled by the
    LS7266R1, such as direction and total count, are available.
    
    Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and
    also clears the counter's respective error flag. Although the counters
    have a 25-bit range, only the lower 24 bits may be set, either directly
    or via a counter's preset attribute. Interrupts are not supported by
    this driver.
    
    This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES
    104-QUAD-4. The base port addresses for the devices may be configured
    via the base array module parameter.
