* 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"; |
|
};
