+* 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";
