+CAAM SNVS Node
+  Load the SECVIO node.
+
+  - compatible
+      Usage: required
+      Value type: <string>
+      Definition: Must include "fsl,imx6q-caam-snvs".
+
+  - reg
+      Usage: required
+      Value type: <prop-encoded-array>
+      Definition: A standard property.  Specifies the physical
+          address and length of the SEC4 configuration
+          registers.

+Security Violation (SECVIO) Node
+  Reports security violations.
+
+  - compatible
+      Usage: required
+      Value type: <string>

+
+   - interrupts
+      Usage: required
+      Value type: <prop_encoded-array>
+      Definition:  Specifies the interrupts generated by this
+           device.  The value of the interrupts property
+           consists of one interrupt specifier. The format
+           of the specifier is defined by the binding document
+           describing the node's interrupt parent.
+
+  - jtag-tamper
+       Usage: optional-but-recommended
+       Value type: <string>
+       Definition:
+           Security tamper on the JTAG
+           Must include "enabled" to enable.
+
+  - watchdog-tamper
+       Usage: optional-but-recommended
+       Value type: <string>
+       Definition:
+           Security tamper on the watchdog
+           Must include "enabled" to enable.
+
+  - internal-boot-tamper
+       Usage: optional-but-recommended
+       Value type: <string>
+       Definition:
+           Security tamper on the internal boot
+           Must include "enabled" to enable.

+  - external-pin-tamper
+       Usage: optional-but-recommended
+       Value type: <string>
+       Definition:
+           Security tamper on the external pin
+           Must include "enabled" to enable.
