config NFC_NCI depends on NFC tristate "NCI protocol support" depends on m default n help NCI (NFC Controller Interface) is a communication protocol between an NFC Controller (NFCC) and a Device Host (DH). Say Y here to compile NCI support into the kernel or say M to compile it as module (nci). config NFC_NCI_SPI depends on NFC_NCI && SPI depends on CRC_CCITT tristate "NCI over SPI protocol support" depends on m default n help NCI (NFC Controller Interface) is a communication protocol between an NFC Controller (NFCC) and a Device Host (DH). Say yes if you use an NCI driver that requires SPI link layer. config NFC_NCI_UART depends on NFC_NCI && TTY tristate "NCI over UART protocol support" depends on m default n help Say yes if you use an NCI driver that requires UART link layer.
