NFC: port100: Add support for type 4A tag platform (2a26f9a2) · Commits · 戴 / test

This adds support for ISO-DEP protocol over NFC-A rf technology. The port100 already supports NFC-A and ATS request and response for type 4A tags are handled at digital level. This patch adds NFC_PROTO_ISO14443 to the supported protocols and an entry for framing configuration which is the same as NFC-A standard frame with CRC handling. Signed-off-by:
