+The Broadcom Secure Processing Unit (SPU) hardware supports symmetric
+cryptographic offload for Broadcom SoCs. A SoC may have multiple SPU hardware
+blocks.
+
+Required properties:
+- compatible: Should be one of the following:
+ brcm,spum-crypto - for devices with SPU-M hardware
+ brcm,spu2-crypto - for devices with SPU2 hardware
+ brcm,spu2-v2-crypto - for devices with enhanced SPU2 hardware features like SHA3
+ and Rabin Fingerprint support
+ brcm,spum-nsp-crypto - for the Northstar Plus variant of the SPU-M hardware
+
+- reg: Should contain SPU registers location and length.
+- mboxes: The mailbox channel to be used to communicate with the SPU.
+ Mailbox channels correspond to DMA rings on the device.
+
+Example:
+ crypto@612d0000 {
+ compatible = "brcm,spum-crypto";
+ reg = <0 0x612d0000 0 0x900>;
+ mboxes = <&pdc0 0>;
+ };

+MediaTek cryptographic accelerators
+
+Required properties:
+- compatible: Should be "mediatek,eip97-crypto"
+- reg: Address and length of the register set for the device
+- interrupts: Should contain the five crypto engines interrupts in numeric
+ order. These are global system and four descriptor rings.
+- clocks: the clock used by the core
+- clock-names: the names of the clock listed in the clocks property. These are
+ "ethif", "cryp"
+- power-domains: Must contain a reference to the PM domain.
+
+
+Example:
+ crypto: crypto@1b240000 {
+ compatible = "mediatek,eip97-crypto";
+ reg = <0 0x1b240000 0 0x20000>;
