From 37ae08c9395420dc1479bca17158a649a771831d Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Thu, 1 Aug 2013 17:07:32 +0200 Subject: ARM: kirkwood: convert the mv88f6281gtw_ge board to DT This commit converts the mv88f6281gtw_ge Kirkwood board to use a Device Tree representation, except for the Ethernet devices and the DSA switch. Even though the mv643xx_eth driver has a DT binding, converting this board to use it is for now left on the side because it doesn't use a simple PHY, but a DSA switch instead.
