config NFC_HCI
       depends on NFC
       tristate "NFC HCI implementation"
       default n
       help
	 Say Y here if you want to build support for a kernel NFC HCI
	 implementation. This is mostly needed for devices that only process
	 HCI frames, like for example the NXP pn544.

config NFC_SHDLC
	depends on NFC_HCI
	select CRC_CCITT
	bool "SHDLC link layer for HCI based NFC drivers"
	default n
	---help---
	  Say yes if you use an NFC HCI driver that requires SHDLC link layer.
	  If unsure, say N here.
NFC: HCI support This is an implementation of ETSI TS 102 622 specification. Many NFC chipsets use HCI as the host <-> target protocol on top of a serial link like i2c.

NFC: SHDLC implementation Most NFC HCI chipsets actually use a simplified HDLC link layer to carry HCI payloads. This implementation registers itself as an HCI device on behalf of the NFC driver.

NFC: Select CRC_CCITT for SHDLC link layer of HCI based drivers The SHDLC link layer of HCI based drivers uses CRC-CCITT and thus needs to select that kernel option. Otherwise it ends up with this linking error: net/built-in.o: In function `nfc_shdlc_add_len_crc': net/nfc/hci/shdlc.c:113: undefined reference to `crc_ccitt' Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Acked-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W.
