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>
Definition: Must include "fsl,imx6q-caam-secvio".
- 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>
