+* Device tree bindings for Texas Instruments da8xx DDR2/mDDR memory controller
+
+The DDR2/mDDR memory controller present on Texas Instruments da8xx SoCs memory
+maps a set of registers which allow to tweak the controller's behavior.
+
+Documentation:
+OMAP-L138 (DA850) - http://www.ti.com/lit/ug/spruh82c/spruh82c.pdf
+
+Required properties:
+
+- compatible:		"ti,da850-ddrctl"
+
+Optional properties:
+
+- ti,pr-old-count:	Priority raise old counter. Specifies the number of
+			memory transfers after which the DDR2/mDDR memory
+			controller will elevate the priority of the oldest
+			command in the command FIFO. Must be between 0-255.
+
+Example for da850 shown below.
+
+ddrctl {
+	compatible = "ti,da850-ddrctl";
+	ti,pr-old-count = <0x20>;
+};
