- * Driver: dt2817
- * Description: Data Translation DT2817
- * Author: ds
- * Status: complete
- * Devices: [Data Translation] DT2817 (dt2817)
- *
- * A very simple digital I/O card.  Four banks of 8 lines, each bank
- * is configurable for input or output.  One wonders why it takes a
- * 50 page manual to describe this thing.
- *
- * The driver (which, btw, is much less than 50 pages) has 1 subdevice
- * with 32 channels, configurable in groups of 8.
- *
- * Configuration options:
- * [0] - I/O port base base address
