1 Marvell Cryptographic Engines And Security Accelerator
2
3 Required properties:
4 - compatible: should be one of the following string
5 "marvell,orion-crypto"
6 "marvell,kirkwood-crypto"
7 "marvell,dove-crypto"
8 "marvell,armada-370-crypto"
9 "marvell,armada-xp-crypto"
10 "marvell,armada-375-crypto"
11 "marvell,armada-38x-crypto"
12 - reg: base physical address of the engine and length of memory mapped
13 region. Can also contain an entry for the SRAM attached to the CESA,
14 but this representation is deprecated and marvell,crypto-srams should
15 be used instead
16 - reg-names: "regs". Can contain an "sram" entry, but this representation
17 is deprecated and marvell,crypto-srams should be used instead
18 - interrupts: interrupt number
19 - clocks: reference to the crypto engines clocks. This property is not
20 required for orion and kirkwood platforms
21 - clock-names: "cesaX" and "cesazX", X should be replaced by the crypto engine
22 id.
23 This property is not required for the orion and kirkwoord
24 platforms.
25 "cesazX" clocks are not required on armada-370 platforms
26 - marvell,crypto-srams: phandle to crypto SRAM definitions
27
28 Optional properties:
29 - marvell,crypto-sram-size: SRAM size reserved for crypto operations, if not
30 specified the whole SRAM is used (2KB)

33 Examples:
34
35 crypto@90000 {
36 compatible = "marvell,armada-xp-crypto";
37 reg = <0x90000 0x10000>;
38 reg-names = "regs";
39 interrupts = <48>, <49>;
40 clocks = <&gateclk 23>, <&gateclk 23>;
41 clock-names = "cesa0", "cesa1";
42 marvell,crypto-srams = <&crypto_sram0>, <&crypto_sram1>;
43 marvell,crypto-sram-size = <0x600>;
