1 | * Atmel HW cryptographic accelerators |
| 2 | ||
| 3 | These are the HW cryptographic accelerators found on some Atmel products. | |
| 4 | ||
| 5 | * Advanced Encryption Standard (AES) | |
| 6 | ||
| 7 | Required properties: | |
| 8 | - compatible : Should be "atmel,at91sam9g46-aes". | |
| 9 | - reg: Should contain AES registers location and length. | |
| 10 | - interrupts: Should contain the IRQ line for the AES. | |
| 11 | - dmas: List of two DMA specifiers as described in | |
| 12 | atmel-dma.txt and dma.txt files. | |
| 13 | - dma-names: Contains one identifier string for each DMA specifier | |
| 14 | in the dmas property. | |
| 15 | ||
| 16 | Example: | |
| 17 | aes@f8038000 { | |
| 18 | compatible = "atmel,at91sam9g46-aes"; | |
| 19 | reg = <0xf8038000 0x100>; | |
| 20 | interrupts = <43 4 0>; | |
| 21 | dmas = <&dma1 2 18>, | |
| 22 | <&dma1 2 19>; | |
| 23 | dma-names = "tx", "rx"; | |

| 25 | * Triple Data Encryption Standard (Triple DES) | |
| 26 | ||
| 27 | Required properties: | |
| 28 | - compatible : Should be "atmel,at91sam9g46-tdes". | |
| 29 | - reg: Should contain TDES registers location and length. | |
| 30 | - interrupts: Should contain the IRQ line for the TDES. | |
| 31 | ||
| 32 | Optional properties: | |
| 33 | - dmas: List of two DMA specifiers as described in | |
| 34 | atmel-dma.txt and dma.txt files. | |
| 35 | - dma-names: Contains one identifier string for each DMA specifier | |
| 36 | in the dmas property. | |
| 37 | ||
| 38 | Example: | |
| 39 | tdes@f803c000 { | |
| 40 | compatible = "atmel,at91sam9g46-tdes"; | |
| 41 | reg = <0xf803c000 0x100>; | |
| 42 | interrupts = <44 4 0>; | |
| 43 | dmas = <&dma1 2 20>, | |
| 44 | <&dma1 2 21>; | |
| 45 | dma-names = "tx", "rx"; | |
| 46 | }; | |

| 48 | * Secure Hash Algorithm (SHA) | |
| 49 | ||
| 50 | Required properties: | |
| 51 | - compatible : Should be "atmel,at91sam9g46-sha". | |
| 52 | - reg: Should contain SHA registers location and length. | |
| 53 | - interrupts: Should contain the IRQ line for the SHA. | |
| 54 | ||
| 55 | Optional properties: | |
| 56 | - dmas: One DMA specifiers as described in | |
| 57 | atmel-dma.txt and dma.txt files. | |
| 58 | - dma-names: Contains one identifier string for each DMA specifier | |
| 59 | in the dmas property. Only one "tx" string needed. | |
| 60 | ||
| 61 | Example: | |
| 62 | sha@f8034000 { | |
| 63 | compatible = "atmel,at91sam9g46-sha"; | |
| 64 | reg = <0xf8034000 0x100>; | |
| 65 | interrupts = <42 4 0>; | |
| 66 | dmas = <&dma1 2 17>; | |
| 67 | dma-names = "tx"; | |
| 68 | }; |
