From 2de584ed31aa0a0b7e3c936286f55245e6ebd58a Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Thu, 6 Nov 2014 13:01:45 +0100 Subject: ARM: dts: omap3-igep00x0: Move outside common file the on board Wifi module. New IGEP boards revisions will use another Wifi module, so this patch moves the DT nodes outside the common omap3-igep.dtsi file to specific DT for every board.
