From acb7ea5eba26696f2f4306624bf176c973a07fe8 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 25 Jun 2014 20:48:33 +0200 Subject: [PATCH] ARM: dts: mxs: Split M28EVK into SoM and EVK parts This patch splits the M28EVK device tree file into a common SoM part and an EVK part. This is needed to make it easier for users of the SoM to put it into different, non-reference baseboard.
