An (*insn_read) can only happen if the subdevice is in a non-busy state,
i.e. an async command is not running. The board reset and subdevice
(*cancel) will ensure that the control bits (devpriv->ctrl) are already
cleared.
The (*insn_read) only needs to enable the software trigger before reading
samples. It should also disable the software trigger when done. Fix the
(*insn_read) to do this.
For aesthetics, rename the function so it has namespace associated with

There are a number of descrepencies in the various manuals for the boards
that this driver supports. Some show a 10 MHz clock for counters 1 and 2
others show a 1 MHz clock. Counter 0 can use either a div 10 of that clock
or an external clock (up to 10 MHz).
Currently this driver initializes counters 1 and 2 with a 10 MHz clock.
For consistency, return 1 MHz (10 MHz/10) for counter 0 when the user
queries the internal clock source with INSN_CONFIG_GET_CLOCK_SRC.

Change the return type to void, this function always succeeds and the
caller does not check the return value anyway.
Fix the initial programming of the control register. The SW bit enables
the software trigger and should not be set here. Setting CNT0 selects the
external clock source for counter 0 (the user counter). It makes more
sense to select the internal 1 MHz clock.
Remove the unnecessary initialization of the private data members. This
function is only called during the (*auto_attach) after the private

The analog outputs can use an external reference to create the D/A output
range. Add an entry to the comedi_lrange table for it and modify the
(*insn_write) to support it.
Note that the D/A output range is 0 to +Vref with a -Vref. The comedi_lrange
does not include the sign of the range. It simmply allows the user to convert
between the 12-bit samples values (0x0000 - 0x0fff) and a physical value (0.0
to 1.0) using the comedilib comedi_to_phys() and comedi_from_phys() functions.
A physical value of 0.0 would actually be 0V with a -Vref and -V with a +Vref
and 1.0 would be +V with a -Vref and 0V with a -Vref. Ths user will need to
work this out but at least they can now use the external reference.

Currently this driver calls pci1710_reset() during the (*detach) of
the driver. That function does the following:
1) program the control register to stop any operations
2) clears the analog input FIFO
3) clears any pending interrupts
4) sets all the analog output channels to unipolar 5V range and 0V output
5) sets all the digital outputs to 0V
Before detaching the comedi core will (*cancel) any running async commands.
This will handle 1-3 above.
Depending on the application, it might not be safe to reset the analog and
digital outputs when the driver is detached.
Remove the board reset when detaching and just use comedi_pci_detach()
directly for the driver (*detach).

The PCI-1760 is board unique. It uses an outgoing/incoming mailbox
programming sequence to access the hardware. The other boards supported
by this driver use simple register mapping. Including support for the
PCI-1760 in this driver just makes it harder to understand.
Separate out the PCI-1760 support into a new driver, adv_pci1760.
Clean up the new driver. The original code had a bunch of CamelCase and
other checkpatch.pl issues.
The code used to access the outgoing/incoming mailboxes was also a bit
awkward with the passing of the arrays for the outgoing and incoming
mailbox bytes. Replace them with two new functions that send a command
and return the feedback data from the command based on the programming
flow chart in the datasheet for the PCI-1760.
The new adv_pci1760 driver also fixes the incomplete timer subdevice.
This subdevice is actually the 2 PWM outputs so the subdevice type
has been changed to COMEDI_SUBD_PWM.
The counter subdevice support was not complete in the original code.
They are also a bit strange since they are up counters connected to
each of the digital inputs. For now that subdevice has been disabled
(COMEDI_SUBD_UNUSED).
