* NFC: Add ISO 14443 type B protocolSamuel Ortiz2012-07-091-5/+7
| | | | | | | | | Some devices (e.g. Sony's PaSoRi) can not do type B polling, so we have to make a distinction between ISO14443 type A and B poll modes. Cc: Eric Lapuyade <eric.lapuyade@intel.com> Cc: Ilan Elias <ilane@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Use communicate thru only for PaSoRi when trying to read Felica tagsSamuel Ortiz2012-07-091-12/+11
| | | | | | Otherwise DATA_EXCHANGE seems to be just fine. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Add initial Sony RC-S360 support to pn533Samuel Ortiz2012-07-091-38/+181
| | | | | | | Sony RC-S360 is also known as the Sony PaSoRi contactless reader. Only type 2, 3 and 4 tag reading is supported at the moment. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Monitor pn533 target modeSamuel Ortiz2012-06-041-1/+22
| | | | | | | When receiving a DEP link down event, we should cancel all pending URBs if we're activated as a target or if we're an initiator. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Convert pn533 from semaphore to mutexSamuel Ortiz2012-06-041-7/+7
| | | | Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Set the proper baud rate when trying to activate pn533 targetsSamuel Ortiz2012-06-041-2/+23
| | | | | | We get the right baud rate from the last polled modulation. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Implement pn533 polling loopSamuel Ortiz2012-06-041-126/+161
| | | | | | | After going through all the modulations, the pn533 driver spends 2 seconds listening for targets. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Add type A and type F parameters for pn533 target modeSamuel Ortiz2012-06-041-1/+24
| | | | | | Without those settings several devices will not activate pn533 as a target. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Add passive initiator data for pn533Samuel Ortiz2012-06-041-5/+18
| | | | | | | When trying to enable a DEP link as a passive initiator, pn533 needs to provide the polling request command payload. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Configure pn533 RF timingsSamuel Ortiz2012-06-041-0/+25
| | | | | | | Those define the ATR_RES response timeout after which the pn533 considers the target to be mute. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Unregister device if pn533 initial configuration failsSamuel Ortiz2012-06-041-1/+5
| | | | Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Reset poll mod list when stopping pn533 pollSamuel Ortiz2012-06-041-0/+2
| | | | Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Implement the pn533 target mode Tx opSamuel Ortiz2012-06-041-9/+73
| | | | Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Implement the pn533 target mode data fetching routineSamuel Ortiz2012-06-041-5/+80
| | | | | | | This one needs to be called as soon as we are activated as a target, for the pn533 to receive the first SYMM and keep the LLCP link alive. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Introduce target mode tx opsSamuel Ortiz2012-06-041-4/+4
| | | | | | And rename the initiator mode data exchange ops for consistency sake. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Add target mode activation netlink eventSamuel Ortiz2012-06-041-2/+25
| | | | | | | | 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>
* NFC: Implement pn533 target mode polling loopSamuel Ortiz2012-06-041-5/+104
| | | | | | We only want to support p2p target mode for now, no host card emulation. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Add target mode protocols to the polling loop startup routineSamuel Ortiz2012-06-041-10/+29
| | | | Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: Remove unneeded pn533 dev NULL checkDan Carpenter2012-05-151-3/+0
| | | | | | | | | | | container_of() works by subtracting the offset of the member. The math can't really return a zero here. Sometimes people check it when they actually meant to check something else but in this case we can just remove the check.

* NFC: Cache the core NFC active target pointer instead of its indexEric Lapuyade2012-05-151-8/+8
| | | | | | | | | | | | The NFC Core now caches the active nfc target pointer, thereby avoiding the need to lookup the target table for each invocation of a driver ops. Consequently, pn533, HCI and NCI now directly receive an nfc_target pointer instead of a target index.

* NFC: pn533 Rx chaining supportSamuel Ortiz2012-04-121-16/+128
| | | | | | | | | | | When buffers on the receiption path exceed 262 bytes, the pn533 uses a chaining mechanism where the initiator has to send NULL data frames to fetch the remaining frames. We do that from a workqueue context while holding the cmd lock. Once the MI bit is gone, we aggregate the queued received skbs.

* NFC: Convert pn533 from tasklet to workqueuesSamuel Ortiz2012-04-121-38/+48
| | | | | | | There is no need for soft IRQ contexts, and workqueues are more flexible. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* NFC: Remove the rf mode parameter from the DEP link up routineSamuel Ortiz2012-03-061-15/+5
| | | | | | | | | 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>

* NFC: Export sensf from pn533Samuel Ortiz2012-03-061-0/+3

* NFC: Clear pn533 target structureSamuel Ortiz2012-03-061-0/+2
| | | | | | | | The polled target structure should be memset to 0 in order to avoid sel_res and sens_res garbage. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * USB: convert some miscellanies drivers to use module_usb_driver()Greg Kroah-Hartman2011-11-181-18/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the remaining USB drivers in the kernel to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.

| | | | | | | | | | | | | | | | | | | | Without an API for setting and getting the local and remote general bytes, drivers won't be able to properly establish a DEP link. This API also allows them to propagate the remote general bytes they get from the DEP link establishment up to the LLCP layer.
