* NFC: Add ISO 14443 type B protocolSamuel Ortiz2012-07-093-8/+12
| | | | | | | | | 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/+11Star

* 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: Allow HCI driver to pre-open pipes to some gatesEric Lapuyade2012-07-091-13/+18
| | | | | | | | | | Some NFC chips will statically create and open pipes for both standard and proprietary gates. The driver can now pass this information to HCI such that HCI will not attempt to create and open them, but will instead directly use the passed pipe ids.

* 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: 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: 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

* NFC: potential integer overflow problem in check_crc()Dan Carpenter2012-05-251-1/+1
| | | | | | | | | If "buf[0]" is 255 then "len" gets set to 0. The call to "crc_ccitt(0xffff, buf, len - 2);" casts the "len - 2" to a high positive number which is ugly. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* NFC: HCI based pn544 driverEric Lapuyade2012-05-153-0/+961
| | | | | | | | | This is an NFC driver for NXP pn544. Unlike pn544.c, this one is based on the NFC HCI and SHDLC kernel layers. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* NFC: Remove unneeded pn533 dev NULL checkDan Carpenter2012-05-151-3/+0Star
| | | | | | | | | | | 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/+5Star
| | | | | | | | | 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.

| | | | | | | | | | | | | Download TI NFC init script during nfcwilink open operation, after the NFC channel is registered with TI shared transport. TI NFC init script is written in BTS format. First, read the chip version via a special vendor specific command. Second, we request the relevant BTS file from the user space, and then send the BTS commands to the chip.

| * USB: convert some miscellanies drivers to use module_usb_driver()Greg Kroah-Hartman2011-11-181-18/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
