-* Device tree bindings for Texas Instruments da8xx DDR2/mDDR memory controller
-
-The DDR2/mDDR memory controller present on Texas Instruments da8xx SoCs features
-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-ddr-controller" - for da850 SoC based boards
-- reg:			a tuple containing the base address of the memory
-			controller and the size of the memory area to map
-
-Example for da850 shown below.
-
-ddrctl {
-	compatible = "ti,da850-ddr-controller";
-	reg = <0xb0000000 0xe8>;
-};
