From 736bb9577407d3556d81c3c3cd57581cd3ae10ea Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Sun, 1 Feb 2015 22:26:12 +0100 Subject: NFC: nci: Support logical connections management In order to communicate with an NFCEE, we need to open a logical connection to it, by sending the NCI_OP_CORE_CONN_CREATE_CMD command to the NFCC. It's left up to the drivers to decide when to close an already opened logical connection.
