From 9d13fedc08f4e2cd9640983c2af8b9e9c64c094b Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Thu, 21 Mar 2013 18:37:00 +0100
Subject: [PATCH 110/121] MIPS: add rt3883 dts files

Add a dtsi file for RT3883 SoC. This SoC is almost the same as RT3050 but has
OHCI/EHCI in favour of the Synopsis DWC2 core. There is also a 3x3 802.11n
wifi core.
