From 383256474f2ba043bdb57a657f9d786df88780f1 Mon Sep 17 00:00:00 2001
From: Rod Whitby <rod@whitby.id.au>
Date: Tue, 29 Jan 2008 17:17:29 +1030
Subject: ixp4xx: Use leds-gpio driver instead of IXP4XX-GPIO-LED driver
These are the only three boards to use the IXP4XX-GPIO-LED driver, and
they can all use the new leds-gpio driver instead with no change in
functionality.
