- * 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: Fri, 20 Nov 2020 14:49:36 +0000
- * Status: works (tested on PCI-7230)
- *
- * 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 - 4 subdevices: 0 - 16 input, 1 - 16 output,
- * 2 - IRQ_IDI0, 3 - IRQ_IDI1
- * 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.
- *
- * Currently, this driver only supports interrupts for PCI-7230.
- *
- * Configuration Options: not applicable, uses comedi PCI auto config
