2014-03-11NFC: 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).

2014-02-16NFC: port100: Add support for type 4A tag platformThierry Escande
This adds support for ISO-DEP protocol over NFC-A rf technology. The port100 already supports NFC-A and ATS request and response for type 4A tags are handled at digital level. This patch adds NFC_PROTO_ISO14443 to the supported protocols and an entry for framing configuration which is the same as NFC-A standard frame with CRC handling.

2014-02-16NFC: digital: Add ISO-DEP support for data exchangeThierry Escande
When a type 4A target is activated, this change adds the ISO-DEP SoD when sending frames and removes it when receiving responses. Chaining is not supported so sent frames are rejected if they exceed remote FSC bytes.

2014-02-16NFC: pn544: i2c: Support PN544 C3 secure firmware downloadArron Wang
PN544 C3 firmwares already contain the command frames to be sent, but as they may exceed the i2c maximum payload, we need to fragment them into secure chunks and send them through the secure write command.

2014-02-16NFC: pn544: Pass hardware variant information when downloading firmwareArron Wang
Different pn544 hardware variant may use different commands to download new firmwares. The C2 does a regular firmware download while the C3 uses a more secure protocol. As a consequence we need to pass the hardware variant from the HCI SW version command reply down to the pn544 i2c layer, in order to use the right protocol at run time.

2014-02-16NFC: digital: Add Digital Layer support for ISO/IEC 15693Mark A. Greer
Add support for ISO/IEC 15693 to the digital layer. The code currently uses single-slot anticollision only since the digital layer infrastructure only supports one tag per adapter (making it pointless to do 16-slot anticollision). The code uses two new framing types: 'NFC_DIGITAL_FRAMING_ISO15693_INVENTORY' and 'NFC_DIGITAL_FRAMING_ISO15693_TVT'. The former is used to tell the driver to prepare for an Inventory command and the ensuing anticollision sequence. The latter is used to tell the driver that the anticollision sequence is over and to prepare for non-inventory commands. Signed-off-by: Mark A.

2014-02-13wcn36xx: Wait longer for SMD commands to completePontus Fuchs
On some wcnss firmwares the start command can take up to 300ms to complete. Currently there is a 200ms timeout for SMD command to complete which causes the start to fail.

2014-02-13wlcore: enable beacon filtering only after receiving a beaconEliad Peller
Enabling beacon filtering before receving a beacon might result in not having a beacon at all for the current connected AP, which prevents the station from entering power-save. Replace the current approach (of starting beacon filtering on init) and configure beacon filering only after bss_conf->dtimper is set (which means mac80211 already parsed a beacon).

2014-02-13wlcore: decrease warning verbosity during recoveryArik Nemtsov

2014-02-13wlcore: consider multiple APs when checking active_link_countEliad Peller

2014-02-13wlcore: don't handle unsetting of default wep keyEliad Peller
mac80211 unsets the default wep key on disassoc. The fw doesn't support this notification, so simply ignore it. The actual flow actually triggers fw recovery in some cases, as mac80211 unsets the default key only after disassoc, when wlvif->sta.hlid, resulting in invalid hlid being passed to the fw.

Bump the min wl18xx fw version to 8.8.0.0.13 This fw is not backward compatible with older firmware (due to api changes), so use bump the firmware name as well.

2014-02-13wlcore/wl12xx/wl18xx: configure iface_combinations per-hwEliad Peller
Each hw supports a different iface combinations. Define the supported combinations in each driver, and save it in wl->iface_combinations. Since each driver defines its own combinations now, it can also define its max supported channels, so we no longer need to save and set it explicitly in wlcore.

2014-02-13wlcore/wl12xx/wl18xx: configure num_links per-hwEliad Peller
Upcoming fw versions will have different max links support (according to the hw). Get ready for it by configuring wl->num_links per-hw, instead of using the const WL12XX_MAX_LINKS. However, continue using WLCORE_MAX_LINKS in order to simplify structs declarations (we use it in multiple bitmaps, and converting them to dynamic arrays is just cumbersome).

2014-02-13wlcore/wl12xx/wl18xx: simplify fw_status handlingEliad Peller
Instead of splitting the fw_status into 2 and using some complex calculations, read the fw status and let each low-level driver (wl12xx/wl18xx) convert it into a common struct. This is required for the upcoming fw api changes, which break the current logic anyway. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-02-13wlcore: AP: don't start mac80211 PS on non-peer HLIDsArik Nemtsov
It seems the wl18xx FW sometimes sends spurious changes on the PSM state of the broadcast HLID. This causes us to search for a station on a non-peer link and fail, causing warnings in our log.

2014-02-13wlcore: cancel Tx watchdog on suspend and rearm on first Tx afterArik Nemtsov
Sometimes a tx_flush during suspend fails, but the FW manages to flush out the packets during the time when the host is supsended. Cancel the Tx-watchdog on suspend to not cause a spurious recovery on resume for that case. Set a flag to reinit the watchdog on the first Tx after resume, so we'll still recover if the FW is not empty and there's indeed a problem.

2014-02-13wlcore: memset wl->rx_filter_enabled to zero after recoveryNadim Zubidat
zero rx_filter_enabled array after recovery to avoid cases were the driver will keep trying to clear a filter which is not configured in FW. Such case will cause consecutive recoveries due to command execution failures.
