-Driver: adl_pci9118
-Description: Adlink PCI-9118DG, PCI-9118HG, PCI-9118HR
-Author: Michal Dobes <dobes@tesnet.cz>
-Devices: [ADLink] PCI-9118DG (pci9118dg), PCI-9118HG (pci9118hg),
-  PCI-9118HR (pci9118hr)
-Status: works
-
-This driver supports AI, AO, DI and DO subdevices.
-AI subdevice supports cmd and insn interface,
-other subdevices support only insn interface.
-For AI:
-- If cmd->scan_begin_src=TRIG_EXT then trigger input is TGIN (pin 46).
-- If cmd->convert_src=TRIG_EXT then trigger input is EXTTRG (pin 44).
-- If cmd->start_src/stop_src=TRIG_EXT then trigger input is TGIN (pin 46).
-- It is not necessary to have cmd.scan_end_arg=cmd.chanlist_len but
-  cmd.scan_end_arg modulo cmd.chanlist_len must by 0.
-- If return value of cmdtest is 5 then you've bad channel list
-  (it isn't possible mixture S.E. and DIFF inputs or bipolar and unipolar
-  ranges).
-
-There are some hardware limitations:
-a) You cann't use mixture of unipolar/bipoar ranges or differencial/single
-   ended inputs.
-b) DMA transfers must have the length aligned to two samples (32 bit),
-   so there is some problems if cmd->chanlist_len is odd. This driver tries
-   bypass this with adding one sample to the end of the every scan and discard
-   it on output but this cann't be used if cmd->scan_begin_src=TRIG_FOLLOW
-   and is used flag TRIG_WAKE_EOS, then driver switch to interrupt driven mode
-   with interrupt after every sample.
-c) If isn't used DMA then you can use only mode where
-   cmd->scan_begin_src=TRIG_FOLLOW.
-
-Configuration options:
-  [0] - PCI bus of device (optional)
-  [1] - PCI slot of device (optional)
-	If bus/slot is not specified, then first available PCI
-	card will be used.
-  [2] - 0= standard 8 DIFF/16 SE channels configuration
-	n = external multiplexer connected, 1 <= n <= 256
-  [3] - 0=autoselect DMA or EOC interrupts operation
-	1 = disable DMA mode
-	3 = disable DMA and INT, only insn interface will work
-  [4] - sample&hold signal - card can generate signal for external S&H board
-	0 = use SSHO(pin 45) signal is generated in onboard hardware S&H logic
-	0 != use ADCHN7(pin 23) signal is generated from driver, number say how
-		long delay is requested in ns and sign polarity of the hold
-		(in this case external multiplexor can serve only 128 channels)
-  [5] - 0=stop measure on all hardware errors
-	2 | = ignore ADOR - A/D Overrun status
