  27 * Driver: das08_cs
  28 * Description: DAS-08 PCMCIA boards
  29 * Author: Warren Jasper, ds, Frank Hess
  30 * Devices: [ComputerBoards] PCM-DAS08 (pcm-das08)
  31 * Status: works
  32 *
  33 * This is the PCMCIA-specific support split off from the
  34 * das08 driver.
  35 *
  36 * Configuration Options: none, uses PCMCIA auto config
  37 *
  38 * Command support does not exist, but could be added for this board.
