Subject: [PATCH v2 3/4] zynq: use GIC device tree bindings
Date: Mon, 22 Oct 2012 16:12:41 -0500 [thread overview]
Message-ID: <20121022211241.GD31538@beefymiracle.amer.corp.natinst.com> (raw)
In-Reply-To: <20121022211040.GA31538@beefymiracle.amer.corp.natinst.com>
The Zynq uses the cortex-a9-gic. This eliminates the need to hardcode
register addresses.
Signed-off-by: Josh Cartwright <josh.cartwright@ni.com>
