/**
* enum nfc_commands - supported nfc commands
*
* @ 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 .
* @ 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 .
