Data Fields
const char *	type
	This member holds controller's type/name.

rtems_vector_number	irq
	This member holds controller's interrupt number.

uint32_t	freq
	This member holds controller's base clock frequency.

bool	close_nonblock
	This member informs whether close operation is blocking or nonblocking. This can be set with RTEMS_CAN_CLOSE_NONBLOCK ioctl.

atomic_uint	flags
	This member holds controller's flags.

atomic_uint	used
	This member holds the number of users using the controller.

uint32_t	ctrlmode
	This member holds the currently set mode. Controller's device driver may set initial modes if needed.

uint32_t	ctrlmode_supported
	This member holds modes supported by the controller. Controller's device driver should set this field. Writing unsuported mode via RTEMS_CAN_CHIP_SET_MODE ioctl results in error.

uint32_t	capabilities
	This member holds controller's capabilities.

rtems_mutex	lock
	This member holds the lock to ensure atomicity of chip operations.

rtems_binary_semaphore	stop_sem
	This member is used by the worker to notify the closed operation is finished.

const struct rtems_can_bittiming_const *	bittiming_const
	This member holds nominal bit timing constants (max/min values)

const struct rtems_can_bittiming_const *	data_bittiming_const
	This member holds data bit timing constants (max/min values)

struct rtems_can_bittiming	bittiming
	This member holds currently set nominal btt timing values.

struct rtems_can_bittiming	data_bittiming
	This member holds currently set data btt timing values.

struct rtems_can_chip_ops	chip_ops
	This member holds chip operations.

struct rtems_can_queue_ends_dev *	qends_dev
	This member holds chip's side of queue ends.

struct rtems_can_user_list_t	can_users
	This member holds the list of chip's users.

struct rtems_can_stats	chip_stats
	This member holds the chip's statistics.

void *	internal
	This member holds chip's specific private structure. This structure defines non generic fields and setting.
