* NFC: remove TI nfcwilink driverRob Herring2017-04-011-11/+0
| | | | | | | | | | | | | | | | | | | | It appears that TI WiLink devices including NFC (WL185x/WL189x) never shipped. The only information I found were announcements in Feb 2012 about the parts. There's been no activity on this driver besided common changes since initially added in Jan 2012. There's also no in users that instantiate the platform device (nor DT bindings). This is a first step in removing TI ST (shared transport) driver in favor of extending the BT hci_ll driver to support WL183x chips.

* NFC: pn533: Separate physical layer from the core implementationMichael Thalmeier2016-04-091-10/+1
| | | | | | | | | | | | | | The driver now has all core stuff isolated in one file, and all the hardware link specifics in another. Writing a pn533 driver on top of another hardware link is now just a matter of adding a new file for that new hardware specifics. The first user of this separation will be the i2c based pn532 driver that reuses pn533 core implementation on top of an i2c layer.

* NFC: st21nfcb: Add driver for STMicroelectronics ST21NFCB NFC chipChristophe Ricard2014-07-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* NFC: ST21NFCA: Add driver for STMicroelectronics ST21NFCA NFC ChipChristophe Ricard2014-04-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | 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.

* NFC: Add a nfc hardware simulation driverThierry Escande2013-06-141-0/+10
| | | | | | | | | | | | 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).
