OMAP SoC DES crypto Module
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should contain "ti,omap4-des"
|
|
- ti,hwmods: Name of the hwmod associated with the DES module
|
|
- reg : Offset and length of the register set for the module
|
|
- interrupts : the interrupt-specifier for the DES module
|
|
- clocks : A phandle to the functional clock node of the DES module
|
|
corresponding to each entry in clock-names
|
|
- clock-names : Name of the functional clock, should be "fck"
|
|
|
|
Optional properties:
|
|
- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
|
|
Documentation/devicetree/bindings/dma/dma.txt
|
|
Each entry corresponds to an entry in dma-names
|
|
- dma-names: DMA request names should include "tx" and "rx" if present
|
|
|
|
Example:
|
|
/* DRA7xx SoC */
|
|
des: des@480a5000 {
|
|
compatible = "ti,omap4-des";
|
|
ti,hwmods = "des";
|
|
reg = <0x480a5000 0xa0>;
|
|
interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
|
|
dmas = <&sdma 117>, <&sdma 116>;
|
|
dma-names = "tx", "rx";
|
|
clocks = <&l3_iclk_div>;
|
|
clock-names = "fck";
|
|
};
