+ * enum nfc_vendor_cmds - supported nfc vendor commands
+ *
+ * @FACTORY_MODE: Allow to set the driver into a mode where no secure element
+ *     are activated. 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.
+ * @HCI_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.
