* 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";
|
|
};
