+* Atmel HW cryptographic accelerators
+
+These are the HW cryptographic accelerators found on some Atmel products.
+
+* Advanced Encryption Standard (AES)
+
+Required properties:
+- compatible : Should be "atmel,at91sam9g46-aes".
+- reg: Should contain AES registers location and length.
+- interrupts: Should contain the IRQ line for the AES.
+- dmas: List of two DMA specifiers as described in
+ atmel-dma.txt and dma.txt files.
+- dma-names: Contains one identifier string for each DMA specifier
+ in the dmas property.
+
+Example:
+aes@f8038000 {
+ compatible = "atmel,at91sam9g46-aes";
+ reg = <0xf8038000 0x100>;
+ interrupts = <43 4 0>;
+ dmas = <&dma1 2 18>,
+ <&dma1 2 19>;
+ dma-names = "tx", "rx";
