From 0c456cfa7ef3f02cb077a2883bd9f5ad1cde3761 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Mon, 2 Apr 2012 14:39:26 +0800 Subject: ARM: imx: rename uart and fec device tree nodes It has been pointed out by device tree maintainer for several times that the generic names 'serial' and 'ethernet' should be used for those devices per ePAPR. Renames imx uart and fec device tree nodes to stop them being bad examples.
