Date: Thu, 20 Dec 2012 09:46:13 -0700
Subject: [PATCH] ARM: dts: Add AES data and documentation for AM33XX
Add the generic AM33XX AES 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 AES module.

+OMAP SoC AES crypto Module
+
+Required properties:
+
+- compatible : Should contain entries for this and backward compatible
+ AES versions:
+ - "ti,omap2-aes" for OMAP2.
+ - "ti,omap3-aes" for OMAP3.
+ - "ti,omap4-aes" for OMAP4 and AM33XX.
+ Note that the OMAP2 and 3 versions are compatible (OMAP3 supports
+ more algorithms) but they are incompatible with OMAP4.
+- ti,hwmods: Name of the hwmod associated with the AES odule
+- 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 AES odule.
+
+Optional properties:
+- dmas: DMA controller phandle and DMA request ordered pairs.
+- dma-names: DMA request names. This string corresponds 1:1 with
+ the ordered pairs in dmas. The string naming is to be
+ "tx" for TX request and "rx" for RX request.
+
+Example:
+ /* AM335x */
+ aes: aes@53500000 {
+ compatible = "ti,omap4-aes";
+ ti,hwmods = "aes";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x53500000 0xa0>;
+ interrupt-parent = <&intc>;
+ interrupts = <102>;
+ dmas = <&edma 6
+ &edma 5>;
+ dma-names = "tx", "rx";
+ };
