* 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";
