1 | OMAP SoC AES crypto Module | ||
2 | |||
3 | Required properties: | ||
4 | |||
5 | - compatible : Should contain entries for this and backward compatible | ||
6 | AES versions: | ||
7 | - "ti,omap2-aes" for OMAP2. | ||
8 | - "ti,omap3-aes" for OMAP3. | ||
9 | - "ti,omap4-aes" for OMAP4 and AM33XX. | ||
10 | Note that the OMAP2 and 3 versions are compatible (OMAP3 supports | ||
11 | more algorithms) but they are incompatible with OMAP4. | ||
12 | - ti,hwmods: Name of the hwmod associated with the AES module | ||
13 | - reg : Offset and length of the register set for the module | ||
14 | - interrupts : the interrupt-specifier for the AES module. | ||
15 | |||
16 | Optional properties: | ||
17 | - dmas: DMA specifiers for tx and rx dma. See the DMA client binding, | ||
18 | Documentation/devicetree/bindings/dma/dma.txt | ||
19 | - dma-names: DMA request names should include "tx" and "rx" if present. | ||
20 | |||
21 | Example: | ||
22 | /* AM335x */ | ||
23 | aes: aes@53500000 { | ||
24 | compatible = "ti,omap4-aes"; | ||
25 | ti,hwmods = "aes"; | ||
26 | reg = <0x53500000 0xa0>; | ||
27 | interrupts = <102>; | ||
28 | dmas = <&edma 6>, | ||
29 | <&edma 5>; | ||
30 | dma-names = "tx", "rx"; | ||
31 | }; | ||
