+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

+      Definition: Must include "fsl,sec-v4.0-dma"

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