2014-07-22NFC: st21nfcb: Add driver for STMicroelectronics ST21NFCB NFC chipChristophe Ricard
Add driver for STMicroelectronics ST21NFCB NFC controller. ST21NFCB is using NCI protocol and a proprietary low level transport protocol called NDLC used on top. NDLC: The protocol defines 2 types of frame: - One type carrying NCI data (referred as DATAFRAME frames). - One type carrying protocol information used for flow control and error control mechanisms (referred as SUPERVISOR frames). After each frame transmission to the NFC controller, the device host SHALL waitfor an ACK (SUPERVISOR frame) reception before sending a new frame. The NFC controller MAY send a frame at anytime to the device host. The NFC controller MAY send a specific WAIT supervisor frame to indicate to device host that a NCI data packet has been received but that it could take significant time before the NFC controller sends an ACK and thus allows next data reception.

2014-04-21NFC: ST21NFCA: Add driver for STMicroelectronics ST21NFCA NFC ChipChristophe Ricard
Add driver for STMicroelectronics ST21NFCA NFC controller. ST21NFCA is using HCI protocol, shdlc as LLC layer & I2C as communication protocol. Adding support for Reader/Writer mode with Tag type 1/2/3/4 A & B. It is using proprietary gate 15 for ISO14443-3 such as type 1 & type 2 tags. It is using proprietary gate 14 for type F tags. ST21NFCA_DEVICE_MGNT_GATE gives access to proprietary CLF configuration. Standard gate for ISO14443-4 A (13) & B (11) are also used. ST21NFCA specific mecanism: One particular point to notice for the data handling is that frame does not contain any length value. Therefore the i2c part of this driver is managing the reception with a read length sequence until the end of frame (0x7e) is reached. In order to avoid conflict between sof & eof a mecanism called byte stuffing concist of an escape byte (0x7d) insertion before special byte (0x7e, 0x7d). The special byte is then xored with 0x20. In this driver, When data are available in the CLF, the interrupt gpio is driven to active state and triggered an interrupt. Once the i2c_master_recv start, the interrupt gpio is driven to idle state until its complete. If the frame is incomplete or data are still available, interrupts will be triggered again.

2014-03-10NFC: trf7970a: Add driver with ISO/IEC 14443 Type 2 Tag SupportMark A. Greer
Add a driver for the Texas Instruments TRF7970a RFID/NFC/15693 transceiver. The driver currently supports ISO/IEC 14443 Type 2 tags only (MIFARE Ultralight and Ultralight C but not Classic).

2013-10-07NFC: Sony Port-100 Series driverThierry Escande
This adds support for the Sony NFC USB dongle RC-S380, based on the Port-100 chip. This dongle is an analog frontend and does not implement the digital layer. This driver uses the nfc_digital module which is an implementation of the NFC Digital Protocol stack. This patch is a skeleton. It only registers the dongle against the NFC digital protocol stack. All NFC digital operation functions are stubbed out.

2013-06-14NFC: Add a nfc hardware simulation driverThierry Escande
This driver declares two virtual NFC devices supporting NFC-DEP protocol. An LLCP connection can be established between them and all packets sent from one device is sent back to the other, acting as loopback devices. Once established, the LLCP link can be disconnected by disabling the target device (with rfkill, nfctool, or neard disable-adapter test script).

2013-04-15NFC: mei: Add a common mei bus API for NFC driversEric Lapuyade
This isolates the common code that is required to use an mei bus nfc device from an NFC HCI drivers. This prepares for future drivers for NFC chips connected behind an Intel Management Engine controller. The microread_mei HCI driver is also modified to use that common code.

2013-01-09NFC: pn544: Separate the core code and the i2c one into different modulesSamuel Ortiz
As we may need to support other physical layers, we can avoid linking the core part into each and every pn544 module. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: Separate pn544 hci driver in HW dependant and independant partsEric Lapuyade
The driver now has all HCI stuff isolated in one file, and all the hardware link specifics in another. Writing a pn544 driver on top of another hardware link is now just a matter of adding a new file for that new hardware specifics.
