2012-04-15net: cleanup unsigned to unsigned intEric Dumazet
Use of "unsigned int" is preferred to bare "unsigned" in net tree. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-04-12NFC: Add Core support to generate tag lost eventEric Lapuyade
Some HW/drivers get notifications when a tag moves out of the radio field. This notification is now forwarded to user space through netlink.

2012-04-12NFC: The core part should generate the target indexSamuel Ortiz
The target index can be used by userspace to uniquely identify a target and thus should be kept unique, per NFC adapter. Moreover, some protocols do not provide a logical index when discovering new targets, so we have to generate one for them. For NCI or pn533 to fetch their logical index, we added a logical_idx field to the target structure. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-12NFC: SHDLC implementationEric Lapuyade
Most NFC HCI chipsets actually use a simplified HDLC link layer to carry HCI payloads. This implementation registers itself as an HCI device on behalf of the NFC driver.

2012-04-12NFC: HCI supportEric Lapuyade
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.

2012-04-12NFC: Export target lost functionEric Lapuyade
NFC drivers will call this routine when they detect that a tag leaves the RF field. This will eventually lead to the corresponding netlink event to be sent.

2012-03-06NFC: Remove the rf mode parameter from the DEP link up routineSamuel Ortiz
When calling nfc_dep_link_up, we implicitely are in initiator mode. Which means we also can provide the general bytes as a function argument, as all drivers will eventually request them. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-01-24NFC: Add NCI multiple targets supportIlan Elias
Add the ability to select between multiple targets in NCI. If only one target is found, it will be auto-activated. If more than one target is found, then DISCOVER_NTF will be generated for each target, and the host should select one by calling DISCOVER_SELECT_CMD. Then, the target will be activated. If the activation fails, GENERIC_ERROR_NTF is generated. Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-01-24NFC: NFC core layer should not set the target_idxIlan Elias
The NFC core layer should not set the target_idx. Instead, the driver layer (e.g. NCI, PN533) should set the target_idx, so that it will be able to identify the target when its I/F (e.g. activate_target) is called. This is required in order to support multiple targets. Note that currently supported drivers (PN533 and NCI) don't use the target_idx in their implementation.

2012-01-24NFC: Clearly separate NCI states from flagsIlan Elias
Make a clear separation between NCI states and flags. This is required in order to support more NCI states (e.g. for multiple targets support). Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-12-14NFC: Set and get DEP general bytesSamuel Ortiz
Without an API for setting and getting the local and remote general bytes, drivers won't be able to properly establish a DEP link.
