    NFC: Add basic NCI over SPI · 8a00a61b
    Frederic Danis authored
    The NFC Forum defines a transport interface based on
    Serial Peripheral Interface (SPI) for the NFC Controller
    Interface (NCI).
    
    This module implements the SPI transport of NCI, calling SPI module
    directly to read/write data to NFC controller (NFCC).
    
    NFCC driver should provide functions performing device open and close.
    It should also provide functions asserting/de-asserting interruption
    to prevent TX/RX race conditions.
    NFCC driver can also fix a delay between transactions if needed by
    the hardware.
