+CAAM DMA Node
+
+ Child node of the crypto node that enables the use of the DMA capabilities
+ of the CAAM by a stand-alone driver. The only required property is the
+ "compatible" property. All the other properties are determined from
+ the job rings on which the CAAM DMA driver depends (ex: the number of
+ dma-channels is equal to the number of defined job rings).

+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Must include "fsl,sec-v4.0-dma"
+
+EXAMPLE

+ compatible = "fsl,sec-v5.4-dma",
