/**

 *
 * @NFC_CMD_UNSPEC: unspecified command
 *
 * @NFC_CMD_GET_DEVICE: request information about a device (requires
 *	%NFC_ATTR_DEVICE_INDEX) or dump request to get a list of all nfc devices
 * @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.
