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 - reg: base physical address of the engine and length of memory mapped
9 region. Can also contain an entry for the SRAM attached to the CESA,
10 but this representation is deprecated and marvell,crypto-srams should
11 be used instead
12 - reg-names: "regs". Can contain an "sram" entry, but this representation
13 is deprecated and marvell,crypto-srams should be used instead
14 - interrupts: interrupt number
15 - clocks: reference to the crypto engines clocks. This property is only
16 required for Dove platforms
17 - marvell,crypto-srams: phandle to crypto SRAM definitions
18
19 Optional properties:
20 - marvell,crypto-sram-size: SRAM size reserved for crypto operations, if not
21 specified the whole SRAM is used (2KB)
22
23 Examples:
24
25 crypto@30000 {
26 compatible = "marvell,orion-crypto";
27 reg = <0x30000 0x10000>;
28 reg-names = "regs";
29 interrupts = <22>;
30 marvell,crypto-srams = <&crypto_sram>;
31 marvell,crypto-sram-size = <0x600>;
