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

In order to align with st21nfca, dts configuration properties
ese_present and uicc_present are made available in st-nci driver.
So far, in early development firmware, because
nci_nfcee_mode_set(DISABLE) was not supported we had to try to
enable it during the secure element discovery phase.
After several trials on commercial and qualified firmware it appears
that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are
properly supported.
Such feature also help us to eventually save some time (~5ms) when
only one secure element is connected.
