Each subdevice has a maximum of 32 channels. * * PCI-7230 - 4 subdevices: 0 - 16 input, 1 - 16 output, * 2 - IRQ_IDI0, 3 - IRQ_IDI1 * PCI-7233 - 1 subdevice: 0 - 32 input * PCI-7234 - 1 subdevice: 0 - 32 output * PCI-7432 - 2 subdevices: 0 - 32 input, 1 - 32 output * PCI-7433 - 2 subdevices: 0 - 32 input, 1 - 32 input * PCI-7434 - 2 subdevices: 0 - 32 output, 1 - 32 output * * 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. * * Currently, this driver only supports interrupts for PCI-7230. * * Configuration Options: not applicable, uses comedi PCI auto config */ #include <linux/module.h> #include <linux/comedi/comedi_pci.h> #include "plx9052.h" /* * Register I/O map (32-bit access only) */ #define PCI7X3X_DIO_REG … #define PCI743X_DIO_REG … #define ADL_PT_CLRIRQ … #define LINTI1_EN_ACT_IDI0 … #define LINTI2_EN_ACT_IDI1 … #define EN_PCI_LINT2H_LINT1H … enum adl_pci7x3x_boardid { … }; struct adl_pci7x3x_boardinfo { … }; static const struct adl_pci7x3x_boardinfo adl_pci7x3x_boards[] = …; struct adl_pci7x3x_dev_private_data { … }; struct adl_pci7x3x_sd_private_data { … }; static void process_irq(struct comedi_device *dev, unsigned int subdev, unsigned short intcsr) { … } static irqreturn_t adl_pci7x3x_interrupt(int irq, void *p_device) { … } static int adl_pci7x3x_asy_cmdtest(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_cmd *cmd) { … } static int adl_pci7x3x_asy_cmd(struct comedi_device *dev, struct comedi_subdevice *s) { … } static int adl_pci7x3x_asy_cancel(struct comedi_device *dev, struct comedi_subdevice *s) { … } /* same as _di_insn_bits because the IRQ-pins are the DI-ports */ static int adl_pci7x3x_dirq_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int adl_pci7x3x_do_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int adl_pci7x3x_di_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int adl_pci7x3x_reset(struct comedi_device *dev) { … } static int adl_pci7x3x_auto_attach(struct comedi_device *dev, unsigned long context) { … } static void adl_pci7x3x_detach(struct comedi_device *dev) { … } static struct comedi_driver adl_pci7x3x_driver = …; static int adl_pci7x3x_pci_probe(struct pci_dev *dev, const struct pci_device_id *id) { … } static const struct pci_device_id adl_pci7x3x_pci_table[] = …; MODULE_DEVICE_TABLE(pci, adl_pci7x3x_pci_table); static struct pci_driver adl_pci7x3x_pci_driver = …; module_comedi_pci_driver(…); MODULE_DESCRIPTION(…) …; MODULE_AUTHOR(…) …; MODULE_LICENSE(…) …;
