+ * 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_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.
