+OMAP SoC DES crypto Module
+
+Required properties:
+
+- 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
+- clock-names : Name of the functional clock, should be "fck"
+
+Optional properties:
+- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
+ Documentation/devicetree/bindings/dma/dma.txt
+ Each entry corresponds to an entry in dma-names
+- dma-names: DMA request names should include "tx" and "rx" if present
+
+Example:
+ /* DRA7xx SoC */
+ des: des@480a5000 {
+ compatible = "ti,omap4-des";
+ ti,hwmods = "des";
+ reg = <0x480a5000 0xa0>;
+ interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
+ dmas = <&sdma 117>, <&sdma 116>;
+ dma-names = "tx", "rx";
+ clocks = <&l3_iclk_div>;
+ clock-names = "fck";
+ };
