Arm TrustZone CryptoCell hardware contains both cryptographic engine (ccree) and true random number generator engine (cctrng).
These are separate engines with some sharing in logic and interface.
cctrng engine may not always be present.
The devicetree documentation is in:
For ccree - Documentation/devicetree/bindings/crypto/arm-cryptocell.txt
For cctrng - Documentation/devicetree/bindings/rng/arm-cctrng.yaml
