  • 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”;
};

  • Eliptic Curve Cryptography (I2C)

Required properties:

  • compatible : must be “atmel,atecc508a”.
  • reg: I2C bus address of the device.
  • clock-frequency: must be present in the i2c controller node.

Example:
atecc508a@c0 {
compatible = “atmel,atecc508a”;
reg = <0xC0>;
};
