[PATCH 2/5] ARM: dts: calxeda: move memory-controller node out of ecx-common.dtsi
From: Robert Richter
Date: Wed Oct 16 2013 - 07:00:23 EST
From: Rob Herring <rob.herring@xxxxxxxxxxx>
The DDR controller is slightly different in ECX-2000 and ECX-1000, so we
need to have different nodes for each platform.

Calxeda DDR memory controller
Properties:
-- compatible : Should be "calxeda,hb-ddr-ctrl"
+- compatible : Should be:
+ - "calxeda,hb-ddr-ctrl" for ECX-1000
+ - "calxeda,ecx-2000-ddr-ctrl" for ECX-2000
- reg : Address and size for DDR controller registers.
- interrupts : Interrupt for DDR controller.
