2013-12-11nfc: Fix FSF address in file headersJeff Kirsher1-3/+1
Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

2013-08-14NFC: netlink: Add result of firmware operation to completion eventEric Lapuyade1-1/+2
Result is added as an NFC_ATTR_FIRMWARE_DOWNLOAD_STATUS attribute containing the standard errno positive value of the completion result. This event will be sent when the firmare download operation is done and will contain the operation result.

2013-08-14NFC: Move nfc_fw_download_done() definition from private to publicEric Lapuyade1-2/+0
This API must be called by NFC drivers, and its prototype was incorrectly placed. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-07-31NFC: netlink: Rename CMD_FW_UPLOAD to CMD_FW_DOWNLOADSamuel Ortiz1-3/+3
Loading a firmware into a target is typically called firmware download, not firmware upload. So we rename the netlink API to NFC_CMD_FW_DOWNLOAD in order to avoid any terminology confusion from userspace. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-14NFC: Add secure element enablement internal APISamuel Ortiz1-0/+3
Called via netlink, this API will enable or disable a specific secure element. When a secure element is enabled, it will handle card emulation and more generically ISO-DEP target mode, i.e. all target mode cases except for p2p target mode. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-14NFC: Send netlink events for secure elements additions and removalsSamuel Ortiz1-0/+3
When an NFC driver or host controller stack discovers a secure element, it will call nfc_add_se(). In order for userspace applications to use these secure elements, a netlink event will then be sent with the SE index and its type. With that information userspace applications can decide wether or not to enable SEs, through their indexes. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-14NFC: Add firmware upload netlink commandEric Lapuyade1-0/+5
As several NFC chipsets can have their firmwares upgraded and reflashed, this patchset adds a new netlink command to trigger that the driver loads or flashes a new firmware. This will allows userspace triggered firmware upgrade through netlink. The firmware name or hint is passed as a parameter, and the driver will eventually fetch the firmware binary through the request_firmware API. The cmd can only be executed when the nfc dev is not in use. Actual firmware loading/flashing is an asynchronous operation. Result of the operation shall send a new event up to user space through the nfc dev multicast socket. During operation, the nfc dev is not openable and thus not usable.

2013-04-26NFC: Move LLCP code to the NFC top level diirectorySamuel Ortiz1-64/+0
And stop making it optional. LLCP is a fundamental part of the NFC specifications and making it optional does not make much sense. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-03-11NFC: llcp: Service Name Lookup netlink interfaceThierry Escande1-0/+14
This adds a netlink interface for service name lookup support. Multiple URIs can be passed nested into the NFC_ATTR_LLC_SDP attribute using the NFC_CMD_LLC_SDREQ netlink command. When the SNL reply is received, a NFC_EVENT_LLC_SDRES event is sent to the user space. URI and SAP tuples are passed back, nested into NFC_ATTR_LLC_SDP attribute.

2012-10-29NFC: Extend netlink interface for LTO, RW, and MIUX parameters supportThierry Escande1-0/+6
NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for a device. LTO must be set before the link is up otherwise -EINPROGRESS is returned. RW and MIUX can be set at anytime and will be passed in subsequent CONNECT and CC messages. If one of the passed parameters is wrong none is set and -EINVAL is returned. Signed-off-by: Thierry Escande <thierry.escande@linux.intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-06-04NFC: Introduce target mode rx data callbackSamuel Ortiz1-0/+7
This routine will be called by drivers whenever they receive data in target mode. This should be unexpected events and as such should be handled by a standalone API (i.e. not as a callback pointer from an existing API). Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-06-04NFC: Add target mode activation netlink eventSamuel Ortiz1-0/+3
Userspace gets a netlink event upon target mode activation. The LLCP layer is also signaled when we get an ATR_REQ in order to get the remote general bytes. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-05-16NFC: Fix LLCP compilation warningjoseph daniel1-1/+1
nfc_llcp_general_bytes is defined in nfc/core.c as: nfc_llcp_general_bytes(struct nfc_dev *dev, size_t *gb_len). as in nfc/nfc.h: nfc_llcp_general_bytes(struct nfc_dev *dev, u8 *gb_len), if CONFIG_NFC_LLCP is not defined. so we got some warnings, net/nfc/core.c:207:2: warning: passing argument 2 of ‘nfc_llcp_general_bytes’ from incompatible pointer type [enabled by default] net/nfc/nfc.h:87:19: note: expected ‘u8 *’ but argument is of type ‘size_t *’ Signed-off-by: joseph daniel <josephdanielwalter@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W.

2012-03-07NFC: Remove the rf mode parameter from the DEP link up routineSamuel Ortiz1-3/+2

2011-12-14NFC: Initial LLCP supportSamuel Ortiz1-0/+54
This patch is an initial implementation for the NFC Logical Link Control protocol. It's also known as NFC peer to peer mode. This is a basic implementation as it lacks SDP (services Discovery Protocol), frames aggregation support, and frame rejecion parsing. Follow up patches will implement those missing features.
