[PATCH 6/6] ARM: dts: imx6: add support for the Ka-Ro electronics 'MB7' baseboard

From: Lothar WaÃmann
Date: Wed Jan 20 2016 - 07:58:01 EST

This baseboard can be used with all TX6 SoMs, but only a certain set
of combinations can be ordered. Add support for these combinations in
mainline, so that users can easily adopt their own combination of SoM
and baseboard themselves.
