8b3fe7b5 IE |
39 | * @NFC_CMD_DEV_UP: turn on the nfc device |

41 | * @NFC_CMD_DEV_DOWN: turn off the nfc device | |
42 | * (requires %NFC_ATTR_DEVICE_INDEX) | |
4d12b8b1 LRV |
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) | |
fc40a8c1 SO |
56 | * @NFC_EVENT_TM_ACTIVATED: event emitted when the adapter is activated in |
57 | * target mode. | |
58 | * @NFC_EVENT_DEVICE_DEACTIVATED: event emitted when the adapter is deactivated | |
59 | * from target mode. | |
52feb444 TE |
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 | |
66 | * returned. | |
390a1bd8 SO |
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. | |
9ea7187c SO |
72 | * @NFC_CMD_FW_DOWNLOAD: Request to Load/flash firmware, or event to inform |
73 | * that some firmware was loaded | |
