| 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>; |
| 32 | status = "okay"; |
| 33 | }; |
