1 The Broadcom Secure Processing Unit (SPU) hardware supports symmetric
2 cryptographic offload for Broadcom SoCs. A SoC may have multiple SPU hardware
6 - compatible: Should be one of the following:
7 brcm,spum-crypto - for devices with SPU-M hardware
8 brcm,spu2-crypto - for devices with SPU2 hardware
9 brcm,spu2-v2-crypto - for devices with enhanced SPU2 hardware features like SHA3
10 and Rabin Fingerprint support
11 brcm,spum-nsp-crypto - for the Northstar Plus variant of the SPU-M hardware
13 - reg: Should contain SPU registers location and length.
14 - mboxes: The mailbox channel to be used to communicate with the SPU.
15 Mailbox channels correspond to DMA rings on the device.
