A SoC may have +multiple SPU hardware blocks. + +Required properties: +- compatible : Should be "brcm,spum-crypto" for devices with SPU-M hardware + (e.g., Northstar2) or "brcm,spum-nsp-crypto" for the Northstar Plus variant + of the SPU-M hardware. + +- reg: Should contain SPU registers location and length. +- mboxes: A list of mailbox channels to be used by the kernel driver. Mailbox +channels correspond to DMA rings on the device. + +Example: + spu-crypto@612d0000 { + compatible = "brcm,spum-crypto"; + reg = <0 0x612d0000 0 0x900>, /* SPU 0 control regs */ + <0 0x612f0000 0 0x900>, /* SPU 1 control regs */ + <0 0x61310000 0 0x900>, /* SPU 2 control regs */ + <0 0x61330000 0 0x900>; /* SPU 3 control regs */ + mboxes = <&pdc0 0>, + <&pdc1 0>, + <&pdc2 0>, + <&pdc3 0>; + }; --
