From af9c8aa67d07adcd3b41fb2934af7af056eabecf Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Sun, 1 Feb 2015 22:26:10 +0100 Subject: NFC: nci: Add NFCEE discover support NFCEEs (NFC Execution Environment) have to be explicitly discovered by sending the NCI_OP_NFCEE_DISCOVER_CMD command. The NFCC will respond to this command by telling us how many NFCEEs are connected to it. Then the NFCC sends a notification command for each and every NFCEE connected. Here we implement support for sending NCI_OP_NFCEE_DISCOVER_CMD command, receiving the response and the potential notifications.
