[PATCH 1/2] ARM: dts: mx5: Split M53EVK into SoM and EVK parts

Marek Vasut marex at denx.de
Wed Jun 25 11:48:32 PDT 2014


This patch splits the M53EVK 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.
