Subject: [PATCH 32/33] NFC: Add ISO 14443 type B protocol
Date: Fri, 6 Jul 2012 22:09:52 +0200 [thread overview]
Message-ID: <1341605393-32056-33-git-send-email-sameo@linux.intel.com> (raw)
In-Reply-To: <1341605393-32056-1-git-send-email-sameo@linux.intel.com>
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.
