- Marvell Cryptographic Engines And Security Accelerator
- Required properties:
- - compatible: should be one of the following string
- "marvell,orion-crypto"
- "marvell,kirkwood-crypto"
- "marvell,dove-crypto"
- "marvell,armada-370-crypto"
- "marvell,armada-xp-crypto"
- "marvell,armada-375-crypto"
- "marvell,armada-38x-crypto"
- - reg: base physical address of the engine and length of memory mapped
- region. Can also contain an entry for the SRAM attached to the CESA,
- but this representation is deprecated and marvell,crypto-srams should
- be used instead
- - reg-names: "regs". Can contain an "sram" entry, but this representation
- is deprecated and marvell,crypto-srams should be used instead
- - interrupts: interrupt number
- - clocks: reference to the crypto engines clocks. This property is not
- required for orion and kirkwood platforms
- - clock-names: "cesaX" and "cesazX", X should be replaced by the crypto engine
- id.
- This property is not required for the orion and kirkwoord
- platforms.
- "cesazX" clocks are not required on armada-370 platforms
- - marvell,crypto-srams: phandle to crypto SRAM definitions
- Optional properties:
- - marvell,crypto-sram-size: SRAM size reserved for crypto operations, if not
- specified the whole SRAM is used (2KB)
- Examples:
- crypto@90000 {
- compatible = "marvell,armada-xp-crypto";
- reg = <0x90000 0x10000>;
- reg-names = "regs";
- interrupts = <48>, <49>;
- clocks = <&gateclk 23>, <&gateclk 23>;
- clock-names = "cesa0", "cesa1";
- marvell,crypto-srams = <&crypto_sram0>, <&crypto_sram1>;
- marvell,crypto-sram-size = <0x600>;
- status = "okay";
- };
