RTIC nodes have a binding doc in Linux kernel:
Documentation/devicetree/bindings/crypto/fsl-sec4.txt

Thus, in theory, "fsl,sec-v4.0-rtic-memory" could be used instead of NULL for
the compat string.
PPC code in arch/powerpc/include/asm/fsl_liodn.h does this.

In practice, this won't make any difference until a RTIC kernel driver is added.

Horia
