Support for Initiator and Target mode with ISO18092 commands support: - ATR_REQ/ATR_RES - PSL_REQ/PSL_RES - DEP_REQ/DEP_RES Work based on net/nfc/digital_dep.c. st21nfca is using: - Gate reader F for P2P in initiator mode. - Gate card F for P2P in target mode. Felica tag and p2p are differentiated with NFCID2. When starting with 01FE it is acting in p2p mode. On complete_target_discovered on ST21NFCA_RF_READER_F_GATE supported_protocols is set to NFC_PROTO_NFC_DEP_MASK for P2P. Tested against: Nexus S, Galaxy S2, Galaxy S3, Galaxy S3 Mini, Nexus 4 & Nexus 5. Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
