1	* Atmel HW cryptographic accelerators
2	
3	These are the HW cryptographic accelerators found on some Atmel products.
4	
5	* Advanced Encryption Standard (AES)
6	
7	Required properties:
8	- compatible : Should be "atmel,at91sam9g46-aes".
9	- reg: Should contain AES registers location and length.
10	- interrupts: Should contain the IRQ line for the AES.
11	- dmas: List of two DMA specifiers as described in
12	        atmel-dma.txt and dma.txt files.
13	- dma-names: Contains one identifier string for each DMA specifier
14	             in the dmas property.
15	
16	Example:
17	aes@f8038000 {
18		compatible = "atmel,at91sam9g46-aes";
19		reg = <0xf8038000 0x100>;
20		interrupts = <43 4 0>;
21		dmas = <&dma1 2 18>,
22		       <&dma1 2 19>;
23		dma-names = "tx", "rx";
24	
25	* Triple Data Encryption Standard (Triple DES)
26	
27	Required properties:
28	- compatible : Should be "atmel,at91sam9g46-tdes".
29	- reg: Should contain TDES registers location and length.
30	- interrupts: Should contain the IRQ line for the TDES.
31	
32	Optional properties:
33	- dmas: List of two DMA specifiers as described in
34	        atmel-dma.txt and dma.txt files.
35	- dma-names: Contains one identifier string for each DMA specifier
36	             in the dmas property.
37	
38	Example:
39	tdes@f803c000 {
40		compatible = "atmel,at91sam9g46-tdes";
41		reg = <0xf803c000 0x100>;
42		interrupts = <44 4 0>;
43		dmas = <&dma1 2 20>,
44		       <&dma1 2 21>;
45		dma-names = "tx", "rx";
46	};
47	
48	* Secure Hash Algorithm (SHA)
49	
50	Required properties:
51	- compatible : Should be "atmel,at91sam9g46-sha".
52	- reg: Should contain SHA registers location and length.
53	- interrupts: Should contain the IRQ line for the SHA.
54	
55	Optional properties:
56	- dmas: One DMA specifiers as described in
57	        atmel-dma.txt and dma.txt files.
58	- dma-names: Contains one identifier string for each DMA specifier
59	             in the dmas property. Only one "tx" string needed.
60	
61	Example:
62	sha@f8034000 {
63		compatible = "atmel,at91sam9g46-sha";
64		reg = <0xf8034000 0x100>;
65		interrupts = <42 4 0>;
66		dmas = <&dma1 2 17>;
67		dma-names = "tx";
68	};
