 * Driver: addi_apci_3501
 * Description: ADDI-DATA APCI-3501 Analog output board
 * Devices: [ADDI-DATA] APCI-3501 (addi_apci_3501)
 * Author: H Hartley Sweeten <hsweeten@visionengravers.com>
 * Updated: Mon, 20 Jun 2016 10:57:01 -0700
 * Status: untested
 *
 * Configuration Options: not applicable, uses comedi PCI auto config
 *
 * This board has the following features:
 *   - 4 or 8 analog output channels
 *   - 2 optically isolated digital inputs
 *   - 2 optically isolated digital outputs
 *   - 1 12-bit watchdog/timer
 *
 * There are 2 versions of the APCI-3501:
 *   - APCI-3501-4  4 analog output channels
 *   - APCI-3501-8  8 analog output channels
 *
 * These boards use the same PCI Vendor/Device IDs. The number of output
 * channels used by this driver is determined by reading the EEPROM on
 * the board.
 *
 * The watchdog/timer subdevice is not currently supported.
