+* 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";
+
+* Triple Data Encryption Standard (Triple DES)
+
+Required properties:
+- compatible : Should be "atmel,at91sam9g46-tdes".
+- reg: Should contain TDES registers location and length.
+- interrupts: Should contain the IRQ line for the TDES.
+
+Optional properties:
+- 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:
+tdes@f803c000 {
+ compatible = "atmel,at91sam9g46-tdes";
+ reg = <0xf803c000 0x100>;
+ interrupts = <44 4 0>;
+ dmas = <&dma1 2 20>,
+ <&dma1 2 21>;
+ dma-names = "tx", "rx";
+};
+
+* Secure Hash Algorithm (SHA)
+
+Required properties:
+- compatible : Should be "atmel,at91sam9g46-sha".
+- reg: Should contain SHA registers location and length.
+- interrupts: Should contain the IRQ line for the SHA.
+
+Optional properties:
+- dmas: One 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. Only one "tx" string needed.
+
+Example:
+sha@f8034000 {
+ compatible = "atmel,at91sam9g46-sha";
+ reg = <0xf8034000 0x100>;
+ interrupts = <42 4 0>;
+ dmas = <&dma1 2 17>;
+ dma-names = "tx";
+};
