From 390a1bd8538132186ddb679cafe9e75b7ef7e2d2 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Wed, 19 Dec 2012 19:11:32 +0100 Subject: NFC: Initial Secure Element API Each NFC adapter can have several links to different secure elements and that property needs to be exported by the drivers. A secure element link can be enabled and disabled, and card emulation will be handled by the currently active one. Otherwise card emulation will be host implemented.
