+Freescale DDR memory controller
+
+Properties:
+
+- compatible   : Should include "fsl,chip-memory-controller" where
+                 chip is the processor (bsc9132, mpc8572 etc.), or
+                 "fsl,qoriq-memory-controller".
+- reg          : Address and size of DDR controller registers
+- interrupts   : Error interrupt of DDR controller
+
+Example 1:
+
+       memory-controller@2000 {
+               compatible = "fsl,bsc9132-memory-controller";
+               reg = <0x2000 0x1000>;
+               interrupts = <16 2 1 8>;
+       };
+
+
+Example 2:
+
+       ddr1: memory-controller@8000 {
+               compatible = "fsl,qoriq-memory-controller-v4.7",
+                               "fsl,qoriq-memory-controller";
+               reg = <0x8000 0x1000>;
+               interrupts = <16 2 1 23>;
+       };
