* NFC: nci: Add dynamic logical connections supportChristophe Ricard2015-02-021-15/+41
| | | | | | | | | | | | | The current NCI core only support the RF static connection. For other NFC features such as Secure Element communication, we may need to create logical connections to the NFCEE (Execution Environment. In order to track each logical connection ID dynamically, we add a linked list of connection info pointers to the nci_dev structure.

* NFC: nci: Add status byte management in case of error.Christophe Ricard2014-12-021-2/+9
| | | | | | | | | The nci status byte was ignored. In case of tag reading for example, if the tag is removed from the antenna there is no way for the upper layers (aka: stack) to get inform about such event.

* NFC: NCI: Fix NCI RF FRAME interface usageVincent Cuissard2014-09-011-2/+5
| | | | | | | | | NCI RF FRAME interface is used for all kind of tags except ISODEP ones. So for all other kind of tags the status byte has to be removed. Signed-off-by: Vincent Cuissard <cuissard@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* nfc: Fix FSF address in file headersJeff Kirsher2013-12-111-2/+1
| | | | | | | | | | | | | | Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

* NFC: NCI: Fix skb->dev usageFrederic Danis2013-06-141-2/+0
| | | | | | | | | | | | | skb->dev is used for carrying a net_device pointer and not an nci_dev pointer. Remove usage of skb-dev to carry nci_dev and replace it by parameter in nci_recv_frame(), nci_send_frame() and driver send() functions. NfcWilink driver is also updated to use those functions.
