-OMAP SoC SHA crypto Module
-
-Required properties:
-
-- compatible : Should contain entries for this and backward compatible
-  SHAM versions:
-  - "ti,omap2-sham" for OMAP2 & OMAP3.
-  - "ti,omap4-sham" for OMAP4 and AM33XX.
-  - "ti,omap5-sham" for OMAP5, DRA7 and AM43XX.
-- ti,hwmods: Name of the hwmod associated with the SHAM module
-- reg : Offset and length of the register set for the module
-- interrupts : the interrupt-specifier for the SHAM module.
-
-Optional properties:
-- dmas: DMA specifiers for the rx dma. See the DMA client binding,
-	Documentation/devicetree/bindings/dma/dma.txt
-- dma-names: DMA request name. Should be "rx" if a dma is present.
-
-Example:
-	/* AM335x */
-	sham: sham@53100000 {
-		compatible = "ti,omap4-sham";
-		ti,hwmods = "sham";
-		reg = <0x53100000 0x200>;
-		interrupts = <109>;
-		dmas = <&edma 36>;
-		dma-names = "rx";
-	};
