+description:
+  The Broadcom Secure Processing Unit (SPU) hardware supports symmetric
+  cryptographic offload for Broadcom SoCs. A SoC may have multiple SPU hardware
+  blocks.

+      - brcm,spum-crypto
+      - brcm,spu2-crypto
+      - brcm,spu2-v2-crypto     # enhanced SPU2 hardware features like SHA3 and Rabin Fingerprint support
+      - brcm,spum-nsp-crypto    # Northstar Plus variant of the SPU-M hardware
