 * Driver: rti800
 * Description: Analog Devices RTI-800/815
 * Devices: [Analog Devices] RTI-800 (rti800), RTI-815 (rti815)
 * Author: David A. Schleef <[email protected]>
 * Status: unknown
 * Updated: Fri, 05 Sep 2008 14:50:44 +0100
 *
 * Configuration options:
 *   [0] - I/O port base address
 *   [1] - IRQ (not supported / unused)
 *   [2] - A/D mux/reference (number of channels)
 *	   0 = differential
 *	   1 = pseudodifferential (common)
 *	   2 = single-ended
 *   [3] - A/D range
 *	   0 = [-10,10]
 *	   1 = [-5,5]
 *	   2 = [0,10]
 *   [4] - A/D encoding
 *	   0 = two's complement
 *	   1 = straight binary
 *   [5] - DAC 0 range
 *	   0 = [-10,10]
 *	   1 = [0,10]
 *   [6] - DAC 0 encoding
 *	   0 = two's complement
 *	   1 = straight binary
 *   [7] - DAC 1 range (same as DAC 0)
 *   [8] - DAC 1 encoding (same as DAC 0)
