Public Attributes
int(*	start_chip )(struct can_chip *chip)
	Starts the chip. Called with RTEMS_CAN_CHIP_START ioctl.

int(*	stop_chip )(struct can_chip *chip)
	Stops the chip. Called with RTEMS_CAN_CHIP_STOP ioctl.

int(*	chip_ioctl )(struct can_chip chip, ioctl_command_t command, void arg)
	Unrecognized ioctl calls are passed to chip specific function to handle them. This way chip specific ioctl calls can be implemented.

int(*	get_chip_timestamp )(struct can_chip chip, uint64_t timestamp)
	Obtains timestamp from the controller. Called with RTEMS_CAN_CHIP_GET_TIMESTAMP ioctl.

int(*	get_chip_info )(struct can_chip *chip, int what)
	Obtains controller's information specified by input integer argument. Called with RTEMS_CAN_CHIP_GET_INFO ioctl.

int(*	calc_bittiming )(struct can_chip chip, int type, struct can_bittiming bt)
	Calculates bit timing from given bit rate and saves the values to controller's registers. Called with RTEMS_CAN_SET_BITRATE ioctl if CAN_BITTIME_FROM_BITRATE is set.

int(*	check_and_set_bittiming )(struct can_chip chip, int type, struct can_bittiming bt)
	Checks bit timing given by user and saves it to controller's registers. Called with RTEMS_CAN_SET_BITRATE ioctl if CAN_BITTIME_FROM_PRECOMPUTED is set.

int(*	set_chip_mode )(struct can_chip *chip, uint32_t mode)
	Sets controller mode defined in input argument. Called with RTEMS_CAN_CHIP_SET_MODE.
