It does not consider any NFC_ATTR_VENDOR_DATA. * @HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes command. * It does not consider any NFC_ATTR_VENDOR_DATA. * @HCI_DM_PUT_DATA: Allow to configure specific CLF registry as for example * RF trimmings or low level drivers configurations (I2C, SPI, SWP). * @HCI_DM_UPDATE_AID: Allow to configure an AID routing into the CLF routing * table following RF technology, CLF mode or protocol. * @HCI_DM_GET_INFO: Allow to retrieve CLF information. * @HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as low * level drivers configurations or RF trimmings. * @HCI_DM_DIRECT_LOAD: Allow to load a firmware into the CLF. A complete * packet can be more than 8KB. * @HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF * configuration changes without CLF power off. * @HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example the * white list). * @HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF * technology. When using this command to anti-collision is done. * @LOOPBACK: Allow to echo a command and test the Dh to CLF connectivity. * @HCI_DM_VDC_MEASUREMENT_VALUE: Allow to measure the field applied on the * CLF antenna. A value between 0 and 0x0f is returned. 0 is maximum. * @HCI_DM_FWUPD_START: Allow to put CLF into firmware update mode. It is a * specific CLF command as there is no GPIO for this. * @HCI_DM_FWUPD_END: Allow to complete firmware update. * @HCI_DM_VDC_VALUE_COMPARISON: Allow to compare the field applied on the * CLF antenna to a reference value. * @MANUFACTURER_SPECIFIC: Allow to retrieve manufacturer specific data * received during a NCI_CORE_INIT_CMD. */ enum nfc_vendor_cmds { … }; struct st_nci_info { … }; void st_nci_remove(struct nci_dev *ndev); int st_nci_probe(struct llt_ndlc *ndlc, int phy_headroom, int phy_tailroom, struct st_nci_se_status *se_status); int st_nci_se_init(struct nci_dev *ndev, struct st_nci_se_status *se_status); void st_nci_se_deinit(struct nci_dev *ndev); int st_nci_discover_se(struct nci_dev *ndev); int st_nci_enable_se(struct nci_dev *ndev, u32 se_idx); int st_nci_disable_se(struct nci_dev *ndev, u32 se_idx); int st_nci_se_io(struct nci_dev *ndev, u32 se_idx, u8 *apdu, size_t apdu_length, se_io_cb_t cb, void *cb_context); int st_nci_hci_load_session(struct nci_dev *ndev); void st_nci_hci_event_received(struct nci_dev *ndev, u8 pipe, u8 event, struct sk_buff *skb); void st_nci_hci_cmd_received(struct nci_dev *ndev, u8 pipe, u8 cmd, struct sk_buff *skb); int st_nci_vendor_cmds_init(struct nci_dev *ndev); #endif /* __LOCAL_ST_NCI_H_ */
