/*
 * Driver: jr3_pci
 * Description: JR3/PCI force sensor board
 * Author: Anders Blomdell <anders.blomdell@control.lth.se>
 * Updated: Thu, 01 Nov 2012 17:34:55 +0000
 * Status: works
 * Devices: [JR3] PCI force sensor board (jr3_pci)
 *
 * Configuration options:
 *   None
 *
 * Manual configuration of comedi devices is not supported by this
 * driver; supported PCI devices are configured as comedi devices
 * automatically.
 *
 * The DSP on the board requires initialization code, which can be
 * loaded by placing it in /lib/firmware/comedi.  The initialization
 * code should be somewhere on the media you got with your card.  One
 * version is available from http://www.comedi.org in the
 * comedi_nonfree_firmware tarball.  The file is called "jr3pci.idm".
