From 4f48b7fc5ab6286ab4a9522928aa1acc163a4bf3 Mon Sep 17 00:00:00 2001 From: Alan M Butler Date: Mon, 20 Aug 2012 15:29:07 +0100 Subject: ARM: Kirkwood: Iomega ix2-200 DT support Add support for the Iomega ix2-200. Led's and buttons working as of kernel 3.6-rc2 the 3 lines in the network interface do seem to be required as removing either causes the network card to not be able to reach the network (at least on my device).

This km_kirkwood design is present in many Keymile products. It is based on the Marvell Bobcat SOC which integrates a Kirkwood CPU next to a big L2 Ethernet Switch. The Kirkwood in the SOC is very similar to the "normal" one, but there are a few differences. This initial support is minimal: the kernel can boot with network (ge0), serial port and NAND functional.
