33 * enum nfc_commands - supported nfc commands
35 * @NFC_CMD_UNSPEC: unspecified command
37 * @NFC_CMD_GET_DEVICE: request information about a device (requires
38 * %NFC_ATTR_DEVICE_INDEX) or dump request to get a list of all nfc devices
39 * @NFC_CMD_DEV_UP: turn on the nfc device
40 * (requires %NFC_ATTR_DEVICE_INDEX)
41 * @NFC_CMD_DEV_DOWN: turn off the nfc device
42 * (requires %NFC_ATTR_DEVICE_INDEX)
43 * @NFC_CMD_START_POLL: start polling for targets using the given protocols
44 * (requires %NFC_ATTR_DEVICE_INDEX and %NFC_ATTR_PROTOCOLS)
45 * @NFC_CMD_STOP_POLL: stop polling for targets (requires
46 * %NFC_ATTR_DEVICE_INDEX)
47 * @NFC_CMD_GET_TARGET: dump all targets found by the previous poll (requires
48 * %NFC_ATTR_DEVICE_INDEX)
49 * @NFC_EVENT_TARGETS_FOUND: event emitted when a new target is found
50 * (it sends %NFC_ATTR_DEVICE_INDEX)
51 * @NFC_EVENT_DEVICE_ADDED: event emitted when a new device is registred
52 * (it sends %NFC_ATTR_DEVICE_NAME, %NFC_ATTR_DEVICE_INDEX and
53 * %NFC_ATTR_PROTOCOLS)
54 * @NFC_EVENT_DEVICE_REMOVED: event emitted when a device is removed
55 * (it sends %NFC_ATTR_DEVICE_INDEX)
56 * @NFC_EVENT_TM_ACTIVATED: event emitted when the adapter is activated in
58 * @NFC_EVENT_DEVICE_DEACTIVATED: event emitted when the adapter is deactivated
60 * @NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device
61 * @NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for
62 * a device. LTO must be set before the link is up otherwise -EINPROGRESS
63 * is returned. RW and MIUX can be set at anytime and will be passed in
64 * subsequent CONNECT and CC messages.
65 * If one of the passed parameters is wrong none is set and -EINVAL is
67 * @NFC_CMD_ENABLE_SE: Enable the physical link to a specific secure element.
68 * Once enabled a secure element will handle card emulation mode, i.e.
69 * starting a poll from a device which has a secure element enabled means
70 * we want to do SE based card emulation.
71 * @NFC_CMD_DISABLE_SE: Disable the physical link to a specific secure element.
72 * @NFC_CMD_FW_DOWNLOAD: Request to Load/flash firmware, or event to inform
73 * that some firmware was loaded
74 * @NFC_EVENT_SE_ADDED: Event emitted when a new secure element is discovered.
75 * This typically will be sent whenever a new NFC controller with either
76 * an embedded SE or an UICC one connected to it through SWP.
77 * @NFC_EVENT_SE_REMOVED: Event emitted when a secure element is removed from
78 * the system, as a consequence of e.g. an NFC controller being unplugged.
79 * @NFC_EVENT_SE_CONNECTIVITY: This event is emitted whenever a secure element
80 * is requesting connectivity access. For example a UICC SE may need to
81 * talk with a sleeping modem and will notify this need by sending this
82 * event. It is then up to userspace to decide if it will wake the modem
84 * @NFC_EVENT_SE_TRANSACTION: This event is sent when an application running on
85 * a specific SE notifies us about the end of a transaction. The parameter
86 * for this event is the application ID (AID).
87 * @NFC_CMD_GET_SE: Dump all discovered secure elements from an NFC controller.
88 * @NFC_CMD_SE_IO: Send/Receive APDUs to/from the selected secure element.
