* 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"; };
