staging: comedi: new adl_pci7x3x driver
Currently the ADLink PCI-7230 and PCI-7432 Isolated Digital I/O Boards are supported using two drivers (adl_pci7230 and adl_pci7432). These drivers are very similar and only differ in the total number of di/do channels provided. This driver combines the support for both boards into one common driver. In addition, it adds PCI PnP support for the other boards in the ADLink PCI-723x and PCI-743x series. This driver only supports the comedi PCI auto config attach mechanism. The legacy attach using the comedi_config utility is not supported or required by this driver.

Status: untested
|

|

This driver only attaches using the PCI PnP auto config support
|
||||
in the comedi core. The module parameter 'comedi_autoconfig'
|
||||
must be 1 (default) to enable this feature. The COMEDI_DEVCONFIG
|
||||
ioctl, used by the comedi_config utility, is not supported by
|
||||
this driver.
|
||||
|
||||
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.
