* NFC: Add basic NCI over SPIFrederic Danis2013-06-14
| | | | | | | | | | | | | | | | | | 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.
