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.

2014-01-07NFC: nfcmrvl: Add setup handlerAmitkumar Karwar
Marvell nfc device provides support for external coexistance control. It allows Device Host to inhibit the NFCC from polling when required by asserting a GPIO pin. A second pin allows the DH to have feedback on the current NFCC state. The required configuration for this feature is done in setup handler.

2014-01-04NFC: pn544: Refactor hw_config valuesArman Uguray
Some of the EEPROM configurations that are assigned by the PN544 driver are set by the firmware and should not be modified by the driver. Others are certain user mode configurations that are currently getting set to values that shouldn't necessarily be dictated by the driver.

2013-10-07NFC: port100: Commands mechanism implementationThierry Escande
This patch implements the command handling mechanism. The digital stack serializes all commands sent to the driver. This means that the digital stack waits for the reply of the current command before sending a new one. So there is no command queue managed at driver level. All Port-100 commands are asynchronous. If the command has been sent successfully to the device, it replies with an ACK frame. Then the command response is received (or actually no-response in case of timeout or error) and a command complete work on the system workqueue is responsible for sending the response (or the error) back to the digital stack. The digital stack requires some commands to be synchronous, mainly hardware configuration ones. These commands use the asynchronous command path but are made synchronous by using a completion object.

2013-10-07NFC: Sony Port-100 Series driverThierry Escande
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.

2013-09-25NFC: pn533: Target mode Tx fragmentation supportOlivier Guiter
In target mode, when we want to send frames larger than the max length (PN533_CMD_DATAEXCH_DATA_MAXLEN), we have to split the frame in smaller chunks and send them, using a specific working queue, with the TgSetMetaData command. TgSetMetaData sets his own MI bit in the PFB. The last chunk is sent using the TgSetData command.

2013-09-25NFC: pn533: Add support for incoming fragmented frame in target modeOlivier Guiter
This code processes, for Target Mode, incoming fragmented frames. If the MI bit is present, we start a working queue to grab and aggregate all the parts (using TmGetData between each parts). On the last one, as there's no more MI bit, we jump on the usual behavior. Signed-off-by: Olivier Guiter <olivier.guiter@linux.intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-08-14NFC: pn533: Add some polling entropySamuel Ortiz
By not always starting the polling loop from the same modulation, we avoid entering infinite loops where devices exporting 2 targets (on 2 different modulations) get the same target activated over and over. If this target is not readable (e.g. a wallet emulating a tag), we will stay in an error loop for ever. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-08-14NFC: pn533: Store the correct frame size (normal vs ext)Olivier Guiter
The extended information frame are sent by PN533 to exchange frames larger than 255 bytes. These extended frame are very close from the standard ones except for the header size length.

2013-08-14NFC: pn533: Add extended information frame decoding supportOlivier Guiter
Extended Information frames are slightly different from standard frames as they can (theorically) handle datas up tu 64kB. PN533 firmware only supports packet data up to 265 (incl.

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...
