In NFC Forum NCI specification, some RF Protocol values are reserved for proprietary use (from 0x80 to 0xfe). Some CLF vendor may need to use one value within this range for specific technology. Furthermore, some CLF may not becompliant with NFC Froum NCI specification 2.0 and therefore will not support RF Protocol value 0x06 for PROTOCOL_T5T as mention in a draft specification and in a recent push. Adding get_rf_protocol handle to the nci_ops structure will help to set the correct technology to target.

NCI RF FRAME interface is used for all kind of tags except ISODEP ones. So for all other kind of tags the status byte has to be removed. Signed-off-by: Vincent Cuissard <cuissard@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
All contexts have to be initiliazed before calling nfc_register_device otherwise it is possible to call nci_dev_up before ending the nci_register_device function. In such case kernel will crash on non initialized variables. Signed-off-by: Vincent Cuissard <cuissard@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

In order to operate at the fasted bit rate possible, add initiator-side support for PSL REQ while in P2P mode. The PSL REQ will switch the RF technology to 424F whenever possible.

Conflicts: net/6lowpan/iphc.c Minor conflicts in iphc.c were changes overlapping with some style cleanups. John W. Linville says: ==================== Please pull this last(?) batch of wireless change intended for the 3.17 stream... For the NFC bits, Samuel says: "This is a rather quiet one, we have: - A new driver from ST Microelectronics for their NCI ST21NFCB, including device tree support. - p2p support for the ST21NFCA driver - A few fixes an enhancements for the NFC digital laye" For the Atheros bits, Kalle says: "Michal and Janusz did some important RX aggregation fixes, basically we were missing RX reordering altogether. The 10.1 firmware doesn't support Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc support with that firmware. Also he implemented a workaround for a KVM issue." For the Bluetooth bits, Gustavo and Johan say: "To quote Gustavo from his previous request: 'Some last minute fixes for -next. We have a fix for a use after free in RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with auto-connection handling. Last, we added support for reading the codec and MWS setting for controllers that support these features.' Additionally there are fixes to LE scanning, an update to conform to the 4.1 core specification as well as fixes for tracking the page scan state. All of these fixes are important for 3.17." And, "We've got: - 6lowpan fixes/cleanups - A couple crash fixes, one for the Marvell HCI driver and another in LE SMP. - Fix for an incorrect connected state check - Fix for the bondable requirement during pairing (an issue which had crept in because of using "pairable" when in fact the actual meaning was "bondable" (these have different meanings in Bluetooth)" Along with those are some late-breaking hardware support patches in brcmfmac and b43 as well as a stray ath9k patch. ==================== Signed-off-by: David S.

The digital layer of the NFC subsystem currently supports a 'tg_listen_mdaa' driver hook that supports devices that can do mode detection and automatic anticollision. However, there are some devices that can do mode detection but not automatic anitcollision so add the 'tg_listen_md' hook to support those devices. In order for the digital layer to get the RF technology detected by the device from the driver, add the 'tg_get_rf_tech' hook. It is only valid to call this hook immediately after a successful call to 'tg_listen_md'. CC: Thierry Escande <thierry.escande@linux.intel.com> Signed-off-by: Mark A.

Add new "NFC_DIGITAL_FRAMING_*" calls to the digital layer so the driver can make the necessary adjustments when performing anticollision while in target mode. The driver must ensure that the effect of these calls happens after the following response has been sent but before reception of the next request begins.
