ARM: dts: AM33XX: Add SHAM data and documentation 



Add the generic AM33XX SHAM module's device tree data and
enable it for the am335x-evm, am335x-evmsk, and am335x-bone
platforms.  Also add Documentation file describing the data
for the SHAM module.

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.

  Note that these two versions are incompatible.

- 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";

	};
