/*
 * Driver: pcl726
 * Description: Advantech PCL-726 & compatibles
 * Author: David A. Schleef <[email protected]>
 * Status: untested
 * Devices: [Advantech] PCL-726 (pcl726), PCL-727 (pcl727), PCL-728 (pcl728),
 *   [ADLink] ACL-6126 (acl6126), ACL-6128 (acl6128)
 *
 * Configuration Options:
 *   [0]  - IO Base
 *   [1]  - IRQ (ACL-6126 only)
 *   [2]  - D/A output range for channel 0
 *   [3]  - D/A output range for channel 1
 *
 * Boards with > 2 analog output channels:
 *   [4]  - D/A output range for channel 2
 *   [5]  - D/A output range for channel 3
 *   [6]  - D/A output range for channel 4
 *   [7]  - D/A output range for channel 5
 *
 * Boards with > 6 analog output channels:
 *   [8]  - D/A output range for channel 6
 *   [9]  - D/A output range for channel 7
 *   [10] - D/A output range for channel 8
 *   [11] - D/A output range for channel 9
 *   [12] - D/A output range for channel 10
 *   [13] - D/A output range for channel 11
 *
 * For PCL-726 the D/A output ranges are:
 *   0: 0-5V, 1: 0-10V, 2: +/-5V, 3: +/-10V, 4: 4-20mA, 5: unknown
 *
 * For PCL-727:
 *   0: 0-5V, 1: 0-10V, 2: +/-5V, 3: 4-20mA
 *
 * For PCL-728 and ACL-6128:
 *   0: 0-5V, 1: 0-10V, 2: +/-5V, 3: +/-10V, 4: 4-20mA, 5: 0-20mA
 *
 * For ACL-6126:
 *   0: 0-5V, 1: 0-10V, 2: +/-5V, 3: +/-10V, 4: 4-20mA
