+- compatible : Should contain "ti,omap4-des"
+- ti,hwmods: Name of the hwmod associated with the DES module
+- reg : Offset and length of the register set for the module
+- interrupts : the interrupt-specifier for the DES module
+- clocks : A phandle to the functional clock node of the DES module
+ corresponding to each entry in clock-names
