For aesthetics, add some whitespace to the subdevice init. Remove the unnecessary comments as well as the initialization of the analog input subdevice 'len_chanlist'. That member is only used by subdevices that support async commands. For aesthetics, rename the analog input subdevice (*insn_read) function. Signed-off-by:

The analog output range is not programmable. The DAC ranges are jumper-settable on the board. For aesthetics, provide a range table for the user with all possible ranges. Signed-off-by:

The hardware uses a switch on the board to select if the analog inputs are bipolar or uinipolar. The gain is programmable to allow the following input ranges: Gain Bipolar Unipolar 0 +/-10V 0 to 10V 1 +/-5V 0 to 5V 2 +/-2.5V 0 to 2.5V 3 +/-1.25V 0 to 1.25V Add the necessary code to the driver to allow the user to select the desired range.

The hardware uses a switch on the board to set the number of analog input channels to either 16 single-ended or 8 differential channels. Currently the switch setting is checked for every (*insn_read) operation to validate the channel number. Check the switch setting during the driver attach and initialize the subdevice accordingly. This allows the core to handle the validation. Signed-off-by:

All the comedi drivers have been converted to use the comedi_8254 module to provide support for the 8254 timers. Remove this unused header. Signed-off-by:

This driver uses an 8254 timer to generate the pacer clock used for analog input data conversion. Convert it to use the comedi_8254 module to provide support for the 8254 timer. The hardware actually has two 8254 devices. Timer B0 is the master for timed conversions, timer B1 sets the scan pacing, and tmer A0 sets the conversion pacing. For the conversion, dev->pacer is used for the "B" timers and a new private data member, dev->counter, is used for the "A" timers. All the divisor values are stored in the dev->pacer. Signed-off-by:

Convert this driver to use the comedi_8254 module to provide the 8254 timer support. Add 'clock_src' and 'gate_src' members to the comedi_8254 data for convienence. Signed-off-by:

Currently this driver uses a spinlock in the 8254 subdevice (*insn_read), (*insn_write), and (*insn_config) functions. The comedi core checks if the subdevice is 'busy', in parse_insn(), before any of the subdevice functions are attempted. Remove the unnecessary spinlock. Signed-off-by:

Some of the hardware supported by this driver include an 8254 timer. For aesthetics, convert it to use the comedi_8254 module to provide support for the 8254 timer. This also fixes the (*insn_read) and (*insn_write) to work like the comedi API expects. Currently they only read or write a single value. It also fixes the (*insn_config). Currently the driver is attempting to handle the configuration instructions GPCT_RESET and GPCT_SET_OPERATION. These are just arbitrary valuse and are not real comedi configuration_ids. They actually coorespond to: GPCT_RESET -> INSN_CONFIG_DIO_OUTPUT GPCT_SET_OPERATION -> INSN_CONFIG_ANALOG_TRIG The number of parameters for the instructions is validated by the comedi core in check_insn_config_length(). GPCT_RESET happens to work (insn->n == 1) but GPCT_SET_OPERATION would fail. The INSN_CONFIG_ANALOG_TRIG expects insn->n == 5 but GPCT_SET_OPERATION in this driver expects insn->n == 2.

The boardinfo for the 8254 timer is overly complex. The 8254 timer always has 3 channels and the 'regs' and 'specflags' members of diosubd_data are not used. The only necessary information is the base 'addr' offset to the 8254 registers. Replace the 's8254' member with an unsigned long 'timer_regbase'. Use that to determine if the board has an 8254 timer during the attach of the driver. Save the 'timer_regbase' in the subdevice 'private' pointer to use in the subdevice functions. For aesthetics, absorb pci_dio_add_8254() into the driver attach function. Signed-off-by:

Only two of the boards supported by this driver have an 8254 counter/timer. Both of these boards have a single 8254 device. Currently the counter subdevice functions are coded to support multiple 8254 devices. This is unnecessary and just complicates the code. Simplfy the subdevice functions to work for a single 8254 counter/timer and refactor the driver (*attach) accordingly. Signed-off-by:

This driver uses an 8254 timer to generate the pacer clock used for analog input data conversion. Convert it to use the comedi_8254 module to provide support for the 8254 timer. Remove the unnecessary programming of timer 0. The private data 'count' value is never set by the driver and the timer is reset to MODE0 when the timers are initialized during the attach of the driver. Remove the unnecessart convert_src check in the (*do_cmdtest). The only valid convert_src is TRIG_TIMER. Signed-off-by:

The hardware supported by this driver includes an 8254 timer. This timer is not currently used, other than setting counters 1 and 2 to MODE4 to ensure that the outputs are high. For aesthetics, convert it to use the comedi_8254 module to provide support for the 8254 timer. This will make it easier to add features later. Signed-off-by:

This driver uses an 8254 timer to generate the pacer clock used for analog input data acquisition. It also provides a comedi_subdevice to allow the user to use channel 0 of the 8254 timer. Currently the subdevice support does not work correctly due to and (*insn_config) that does not follow the comedi API. Convert it to use the comedi_8254 module to provide support for the 8254 timer and proper support for the subdevice. Signed-off-by:

This driver uses two 8254 timers. One to generate the analog input pacer clock and one to count the number of samples. Convert it to use the comedi_8254 module to provide support for the 8254 timers. Use the comedi_device 'pacer' member for the 8254 timer used for analog input. This data is freed automatically by the core during the detach of the driver. Store the data for the 8254 timer used to count samples in the private data. This data needs to be freed by the driver when it is detached. Signed-off-by:

This driver uses an 8254 timer to generate the pacer clock used for analog input data acquisition. Convert it to use the comedi_8254 module to provide support for the 8254 timer. Note that the pacer does not have to be stopped when starting a new async command in pcl818_ai_cmd() or when the card is initialy reset by pcl818_reset(). The counters are all reset when the driver is initially attached and the counters used by the pacer are stopped when a command is canceled. Signed-off-by:

Add a new member to the comedi_device struct for a comedi_8254 'pacer'. This provides a convient place to store the data allocated by the comedi_8254 module for boards that use an 8254 device to create the data acquisition pacer clock. Automatically free this pointer in comedi_device_detach_cleanup() so that the drivers don't need to do it when then are detached. Signed-off-by:
