| 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) |
| 31 | |
| 32 | |
| 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>; |
| 44 | status = "okay"; |
| 45 | }; |
