NFC: add nfc subsystem core The NFC subsystem core is responsible for providing the device driver interface. It is also responsible for providing an interface to the control operations and data exchange.

NFC: basic NCI protocol implementation The NFC Controller Interface (NCI) is a standard communication protocol between an NFC Controller (NFCC) and a Device Host (DH), defined by the NFC Forum. Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

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: Digital Protocol stack implementation This is the initial commit of the NFC Digital Protocol stack implementation. It offers an interface for devices that don't have an embedded NFC Digital protocol stack. The driver instantiates the digital stack by calling nfc_digital_allocate_device(). Within the nfc_digital_ops structure, the driver specifies a set of function pointers for driver operations. These functions must be implemented by the driver and are: in_configure_hw: Hardware configuration for RF technology and communication framing in initiator mode. This is a synchronous function. in_send_cmd: Initiator mode data exchange using RF technology and framing previously set with in_configure_hw. The peer response is returned through callback cb. If an io error occurs or the peer didn't reply within the specified timeout (ms), the error code is passed back through the resp pointer. This is an asynchronous function. tg_configure_hw: Hardware configuration for RF technology and communication framing in target mode. This is a synchronous function. tg_send_cmd: Target mode data exchange using RF technology and framing previously set with tg_configure_hw. The peer next command is returned through callback cb. If an io error occurs or the peer didn't reply within the specified timeout (ms), the error code is passed back through the resp pointer. This is an asynchronous function. tg_listen: Put the device in listen mode waiting for data from the peer device. This is an asynchronous function. tg_listen_mdaa: If supported, put the device in automatic listen mode with mode detection and automatic anti-collision. In this mode, the device automatically detects the RF technology and executes the anti-collision detection using the command responses specified in mdaa_params. The mdaa_params structure contains SENS_RES, NFCID1, and SEL_RES for 106A RF tech. NFCID2 and system code (sc) for 212F and 424F. The driver returns the NFC-DEP ATR_REQ command through cb. The digital stack deducts the RF tech by analyzing the SoD of the frame containing the ATR_REQ command. This is an asynchronous function. switch_rf: Turns device radio on or off. The stack does not call explicitly switch_rf to turn the radio on. A call to in|tg_configure_hw must turn the device radio on. abort_cmd: Discard the last sent command. Then the driver registers itself against the digital stack by using nfc_digital_register_device() which in turn registers the digital stack against the NFC core layer. The digital stack implements common NFC operations like dev_up(), dev_down(), start_poll(), stop_poll(), etc. This patch is only a skeleton and NFC operations are just stubs.

NFC Digital: Add initiator NFC-DEP support This adds support for NFC-DEP protocol in initiator mode for NFC-A and NFC-F technologies. When a target is detected, the process flow is as follow: For NFC-A technology: 1 - The digital stack receives a SEL_RES as the reply of the SEL_REQ command. 2 - If b7 of SEL_RES is set, the peer device is configure for NFC-DEP protocol. NFC core is notified through nfc_targets_found(). Execution continues at step 4. 3 - Otherwise, it's a tag and the NFC core is notified. Detection ends. 4 - The digital stacks sends an ATR_REQ command containing a randomly generated NFCID3 and the general bytes obtained from the LLCP layer of NFC core. For NFC-F technology: 1 - The digital stack receives a SENSF_RES as the reply of the SENSF_REQ command. 2 - If B1 and B2 of NFCID2 are 0x01 and 0xFE respectively, the peer device is configured for NFC-DEP protocol. NFC core is notified through nfc_targets_found(). Execution continues at step 4. 3 - Otherwise it's a type 3 tag. NFC core is notified. Detection ends. 4 - The digital stacks sends an ATR_REQ command containing the NFC-F NFCID2 as NFCID3 and the general bytes obtained from the LLCP layer of NFC core. For both technologies: 5 - The digital stacks receives the ATR_RES response containing the NFCID3 and the general bytes of the peer device. 6 - The digital stack notifies NFC core that the DEP link is up through nfc_dep_link_up(). 7 - The NFC core performs data exchange through tm_transceive(). 8 - The digital stack sends a DEP_REQ command containing an I PDU with the data from NFC core. 9 - The digital stack receives a DEP_RES command 10 - If the DEP_RES response contains a supervisor PDU with timeout extension request (RTOX) the digital stack sends a DEP_REQ command containing a supervisor PDU acknowledging the RTOX request. The execution continues at step 9. 11 - If the DEP_RES response contains an I PDU, the response data is passed back to NFC core through the response callback. The execution continues at step 8.
