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