    NFC Digital: Add NFC-F technology support · 8c0695e4
    Thierry Escande authored
    This adds polling support for NFC-F technology at 212 kbits/s and 424
    kbits/s. A user space application like neard can send type 3 tag
    commands through the NFC core.
    Process flow for NFC-F detection is as follow:
    1 - The digital stack sends the SENSF_REQ command to the NFC device.
    2 - A peer device replies with a SENSF_RES response.
    3   - The digital stack notifies the NFC core of the presence of a
          target in the operation field and passes the target NFCID2.
    This also adds support for CRC calculation of type CRC-F. The CRC
    calculation is handled by the digital stack if the NFC device doesn't
    support it.
