Remove the SDF_COMMON flag, the analog reference is not programmable and the default aref (AREF_GROUND -> SDF_GROUND) provides adequate information about the reference. Signed-off-by:

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. Signed-off-by:

Rename this function so it has namespace associated with the driver. For aesthetics, move the function so it is located in the middle of the analog input support functions. Signed-off-by:

The pci1711/31 boards are the only ones that have a smaller FIFO (1K vs 4K) and single-ended analog inputs (no differential). Replace the 'has_large_fifo' and 'has_diff_ai' members of the boardinfo with 'is_pci1711' and use that to determine how to initialize the analog input subdev_flags as well as the private data 'max_samples'.

This member of the boardinfo isn't really necessary. All the boards except the pci1713 have 16 digital inputs and 16 digital outputs. There is already a 'is_pci1713' member in the boardinfo so that can be used to determine the subdevices for the digital inputs and outputs need to be allocated and initialized. Signed-off-by:

The gain codes used to program the analog output range are currently stored in const char arrays. The values look a bit "magic" and it's not clear how they associate with the comedi_lrange without looking through user manuals. Refactor the ai range programming to clarify the driver and remove the magic numbers. Also, refine the bits in the range register that set the differential and unipolar modes. Signed-off-by:

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). Signed-off-by:

All the boards supported by this driver have a 8254 counter. Channels 1 and 2 are used to create the cascaded 32-bit analog input pacer. Counter 0 is available for the user on all the boards except the PCI-1713. Remove the 'has_counter' boardinfo and use the 'is_pci1713' boardinfo to determine if the user counter subdevice needs to be allocated and initialized. Signed-off-by:

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). Signed-off-by:

There are over-commenting in the wilc_wfi_cfgoperations.c file and most of them are not helpful to explain what the code does and generate 80 ending line over warnings. So, all of comments are removed in this patch and the comments will later be added if necessary with the preferred Linux style. Signed-off-by:
