The number of output * channels used by this driver is determined by reading the EEPROM on * the board. * * The watchdog/timer subdevice is not currently supported. */ #include <linux/module.h> #include <linux/comedi/comedi_pci.h> #include "amcc_s5933.h" /* * PCI bar 1 register I/O map */ #define APCI3501_AO_CTRL_STATUS_REG … #define APCI3501_AO_CTRL_BIPOLAR … #define APCI3501_AO_STATUS_READY … #define APCI3501_AO_DATA_REG … #define APCI3501_AO_DATA_CHAN(x) … #define APCI3501_AO_DATA_VAL(x) … #define APCI3501_AO_DATA_BIPOLAR … #define APCI3501_AO_TRIG_SCS_REG … #define APCI3501_TIMER_BASE … #define APCI3501_DO_REG … #define APCI3501_DI_REG … /* * AMCC S5933 NVRAM */ #define NVRAM_USER_DATA_START … #define NVCMD_BEGIN_READ … #define NVCMD_LOAD_LOW … #define NVCMD_LOAD_HIGH … /* * Function types stored in the eeprom */ #define EEPROM_DIGITALINPUT … #define EEPROM_DIGITALOUTPUT … #define EEPROM_ANALOGINPUT … #define EEPROM_ANALOGOUTPUT … #define EEPROM_TIMER … #define EEPROM_WATCHDOG … #define EEPROM_TIMER_WATCHDOG_COUNTER … struct apci3501_private { … }; static const struct comedi_lrange apci3501_ao_range = …; static int apci3501_wait_for_dac(struct comedi_device *dev) { … } static int apci3501_ao_insn_write(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int apci3501_di_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int apci3501_do_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static void apci3501_eeprom_wait(unsigned long iobase) { … } static unsigned short apci3501_eeprom_readw(unsigned long iobase, unsigned short addr) { … } static int apci3501_eeprom_get_ao_n_chan(struct comedi_device *dev) { … } static int apci3501_eeprom_insn_read(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int apci3501_reset(struct comedi_device *dev) { … } static int apci3501_auto_attach(struct comedi_device *dev, unsigned long context_unused) { … } static void apci3501_detach(struct comedi_device *dev) { … } static struct comedi_driver apci3501_driver = …; static int apci3501_pci_probe(struct pci_dev *dev, const struct pci_device_id *id) { … } static const struct pci_device_id apci3501_pci_table[] = …; MODULE_DEVICE_TABLE(pci, apci3501_pci_table); static struct pci_driver apci3501_pci_driver = …; module_comedi_pci_driver(…); MODULE_DESCRIPTION(…) …; MODULE_AUTHOR(…) …; MODULE_LICENSE(…) …;
