From: Mark A. Greer mgr...@animalcreek.com
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
+- interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this module.
+- interrupts : the interrupt number for the SHAM module.
+
+Optional properties:
+- dmas: DMA controller phandle and DMA request ordered pair.
+ Only one rx pair is valid per SHAM module.
+- dma-names: DMA request name. This string corresponds 1:1 with
+ the ordered pair in dmas. The string naming is to be
+ rx for RX request.
+
+Example:
+ /* AM335x */
+ sham: sham@5310 {
+ compatible = ti,omap4-sham;
+ ti,hwmods = sham;
+ reg = 0x5310 0x200;
+ interrupt-parent = intc;
+ interrupts = 109;
+ dmas = edma 36;
+ dma-names = rx;
+ };
