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.
