Subject: [PATCH 8/8] NFC: Add Intel FieldsPeak NFC solution driver
Date: Tue, 24 Feb 2015 12:01:52 +0200	[thread overview]
Message-ID: <1424772112-27399-9-git-send-email-robert.dolca@intel.com> (raw)
In-Reply-To: <1424772112-27399-1-git-send-email-robert.dolca@intel.com>

The device can be enumerated using ACPI using the id INT339A.
The 1st GPIO is the IRQ and the 2nd is the RESET pin.
I can be also enumerated using platform init.
