Add the generic AM33XX SHAM module's device tree data and
|
|
enable it for the am335x-evm, am335x-evmsk, and am335x-bone
|
|
platforms. Also add Documentation file describing the data
|
|
for the SHAM module.

|
+OMAP SoC SHA crypto Module
|
|
+
|
|
+Required properties:
|
|
+
|
|
+- compatible : Should contain entries for this and backward compatible
|
|
+ SHAM versions:
|
|
+ - "ti,omap2-sham" for OMAP2 & OMAP3.
|
|
+ - "ti,omap4-sham" for OMAP4 and AM33XX.
|
|
+ Note that these two versions are incompatible.
|
|
+- ti,hwmods: Name of the hwmod associated with the SHAM module
|
|
+- reg : Offset and length of the register set for the module
|
|
+- interrupts : the interrupt-specifier for the SHAM module.
|
|
+
|
|
+Optional properties:
|
|
+- dmas: DMA specifiers for the rx dma. See the DMA client binding,
|
|
+ Documentation/devicetree/bindings/dma/dma.txt
|
|
+- dma-names: DMA request name. Should be "rx" if a dma is present.
|
|
+
|
|
+Example:
|
|
+ /* AM335x */
|
|
+ sham: sham@53100000 {
|
|
+ compatible = "ti,omap4-sham";
|
|
+ ti,hwmods = "sham";
|
|
+ reg = <0x53100000 0x200>;
|
|
+ interrupts = <109>;
|
|
+ dmas = <&edma 36>;
|
|
+ dma-names = "rx";
|
|
+ };
