+ * Driver: adl_pci7x3x
+ * Description: 32/64-Channel Isolated Digital I/O Boards
+ * Devices: [ADLink] PCI-7230 (adl_pci7230), PCI-7233 (adl_pci7233),
+ * PCI-7234 (adl_pci7234), PCI-7432 (adl_pci7432), PCI-7433 (adl_pci7433),
+ * PCI-7434 (adl_pci7434)
+ * Author: H Hartley Sweeten <hsweeten@visionengravers.com>
+ * Updated: Thu, 02 Aug 2012 14:27:46 -0700
+ * Status: untested
+ *
+ * One or two subdevices are setup by this driver depending on
+ * the number of digital inputs and/or outputs provided by the
+ * board. Each subdevice has a maximum of 32 channels.
+ *
+ * PCI-7230 - 2 subdevices: 0 - 16 input, 1 - 16 output
+ * PCI-7233 - 1 subdevice: 0 - 32 input
+ * PCI-7234 - 1 subdevice: 0 - 32 output
+ * PCI-7432 - 2 subdevices: 0 - 32 input, 1 - 32 output
+ * PCI-7433 - 2 subdevices: 0 - 32 input, 1 - 32 input
+ * PCI-7434 - 2 subdevices: 0 - 32 output, 1 - 32 output
+ *
+ * The PCI-7230, PCI-7432 and PCI-7433 boards also support external
+ * interrupt signals on digital input channels 0 and 1. The PCI-7233
+ * has dual-interrupt sources for change-of-state (COS) on any 16
+ * digital input channels of LSB and for COS on any 16 digital input
+ * lines of MSB. Interrupts are not currently supported by this
+ * driver.
+ *
+ * Configuration Options: not applicable, uses comedi PCI auto config
