1*c66ec88fSEmmanuel VadotOMAP SoC DES crypto Module
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotRequired properties:
4*c66ec88fSEmmanuel Vadot
5*c66ec88fSEmmanuel Vadot- compatible : Should contain "ti,omap4-des"
6*c66ec88fSEmmanuel Vadot- ti,hwmods: Name of the hwmod associated with the DES module
7*c66ec88fSEmmanuel Vadot- reg : Offset and length of the register set for the module
8*c66ec88fSEmmanuel Vadot- interrupts : the interrupt-specifier for the DES module
9*c66ec88fSEmmanuel Vadot- clocks : A phandle to the functional clock node of the DES module
10*c66ec88fSEmmanuel Vadot           corresponding to each entry in clock-names
11*c66ec88fSEmmanuel Vadot- clock-names : Name of the functional clock, should be "fck"
12*c66ec88fSEmmanuel Vadot
13*c66ec88fSEmmanuel VadotOptional properties:
14*c66ec88fSEmmanuel Vadot- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
15*c66ec88fSEmmanuel Vadot	Documentation/devicetree/bindings/dma/dma.txt
16*c66ec88fSEmmanuel Vadot	Each entry corresponds to an entry in dma-names
17*c66ec88fSEmmanuel Vadot- dma-names: DMA request names should include "tx" and "rx" if present
