             * @NFC_EVENT_SE_CONNECTIVITY: This event is emitted whenever a secure element

            
             *	is requesting connectivity access. For example a UICC SE may need to

            
             *	talk with a sleeping modem and will notify this need by sending this

            
             *	event. It is then up to userspace to decide if it will wake the modem

            
             *	up or not.

            
             * @NFC_EVENT_SE_TRANSACTION: This event is sent when an application running on

            
             *	a specific SE notifies us about the end of a transaction. The parameter

             * @NFC_CMD_VENDOR: Vendor specific command, to be implemented directly

	*
	* @NFC_CMD_UNSPEC: unspecified command
	*
	* @NFC_CMD_GET_DEVICE: request information about a device (requires

	* @NFC_CMD_DEV_UP: turn on the nfc device
	* (requires %NFC_ATTR_DEVICE_INDEX)
	* @NFC_CMD_DEV_DOWN: turn off the nfc device
	* (requires %NFC_ATTR_DEVICE_INDEX)
	* @NFC_CMD_START_POLL: start polling for targets using the given protocols
	* (requires %NFC_ATTR_DEVICE_INDEX and %NFC_ATTR_PROTOCOLS)
	* @NFC_CMD_STOP_POLL: stop polling for targets (requires
	* %NFC_ATTR_DEVICE_INDEX)
	* @NFC_CMD_GET_TARGET: dump all targets found by the previous poll (requires
	* %NFC_ATTR_DEVICE_INDEX)
	* @NFC_EVENT_TARGETS_FOUND: event emitted when a new target is found
	* (it sends %NFC_ATTR_DEVICE_INDEX)
	* @NFC_EVENT_DEVICE_ADDED: event emitted when a new device is registred
	* (it sends %NFC_ATTR_DEVICE_NAME, %NFC_ATTR_DEVICE_INDEX and
	* %NFC_ATTR_PROTOCOLS)
	* @NFC_EVENT_DEVICE_REMOVED: event emitted when a device is removed
	* (it sends %NFC_ATTR_DEVICE_INDEX)
	* @NFC_EVENT_TM_ACTIVATED: event emitted when the adapter is activated in
	* target mode.
	* @NFC_EVENT_DEVICE_DEACTIVATED: event emitted when the adapter is deactivated
	* from target mode.
	* @NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device
	* @NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for
	* a device. LTO must be set before the link is up otherwise -EINPROGRESS
	* is returned. RW and MIUX can be set at anytime and will be passed in
	* subsequent CONNECT and CC messages.
	* If one of the passed parameters is wrong none is set and -EINVAL is
	* returned.
	* @NFC_CMD_ENABLE_SE: Enable the physical link to a specific secure element.
	* Once enabled a secure element will handle card emulation mode, i.e.
	* starting a poll from a device which has a secure element enabled means
	* we want to do SE based card emulation.
	* @NFC_CMD_DISABLE_SE: Disable the physical link to a specific secure element.
	* @NFC_CMD_FW_DOWNLOAD: Request to Load/flash firmware, or event to inform
	* that some firmware was loaded
	* @NFC_EVENT_SE_ADDED: Event emitted when a new secure element is discovered.
	* This typically will be sent whenever a new NFC controller with either
	* an embedded SE or an UICC one connected to it through SWP.
	* @NFC_EVENT_SE_REMOVED: Event emitted when a secure element is removed from
	* the system, as a consequence of e.g. an NFC controller being unplugged.
	* @NFC_EVENT_SE_CONNECTIVITY: This event is emitted whenever a secure element
	* is requesting connectivity access. For example a UICC SE may need to
	* talk with a sleeping modem and will notify this need by sending this
	* event. It is then up to userspace to decide if it will wake the modem
	* up or not.
	* @NFC_EVENT_SE_TRANSACTION: This event is sent when an application running on
	* a specific SE notifies us about the end of a transaction. The parameter
	* for this event is the application ID (AID).
	* @NFC_CMD_GET_SE: Dump all discovered secure elements from an NFC controller.
	* @NFC_CMD_SE_IO: Send/Receive APDUs to/from the selected secure element.
	* @NFC_CMD_ACTIVATE_TARGET: Request NFC controller to reactivate target.
	* @NFC_CMD_VENDOR: Vendor specific command, to be implemented directly
	* from the driver in order to support hardware specific operations.
	* @NFC_CMD_DEACTIVATE_TARGET: Request NFC controller to deactivate target.
