| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Should be "inside-secure,safexcel-eip197b", |
| 5 | "inside-secure,safexcel-eip197d" or |
| 6 | "inside-secure,safexcel-eip97ies". |
| 7 | - reg: Base physical address of the engine and length of memory mapped region. |
| 8 | - interrupts: Interrupt numbers for the rings and engine. |
| 9 | - interrupt-names: Should be "ring0", "ring1", "ring2", "ring3", "eip", "mem". |
| 10 | |
| 11 | Optional properties: |
| 12 | - clocks: Reference to the crypto engine clocks, the second clock is |
| 13 | needed for the Armada 7K/8K SoCs. |
| 14 | - clock-names: mandatory if there is a second clock, in this case the |
| 15 | name must be "core" for the first clock and "reg" for |
| 16 | the second one. |
| 17 | |
| 18 | Backward compatibility: |
| 19 | Two compatibles are kept for backward compatibility, but shouldn't be used for |
| 20 | new submissions: |
| 21 | - "inside-secure,safexcel-eip197" is equivalent to |
| 22 | "inside-secure,safexcel-eip197b". |
| 23 | - "inside-secure,safexcel-eip97" is equivalent to |
| 24 | "inside-secure,safexcel-eip97ies". |
| 25 | |
| 26 | Example: |
| 27 | |
| 28 | crypto: crypto@800000 { |
| 29 | compatible = "inside-secure,safexcel-eip197b"; |
| 30 | reg = <0x800000 0x200000>; |
| 31 | interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>, |
| 32 | <GIC_SPI 54 IRQ_TYPE_LEVEL_HIGH>, |
| 33 | <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>, |
| 34 | <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>, |
| 35 | <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>, |
| 36 | <GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>; |
| 37 | interrupt-names = "mem", "ring0", "ring1", "ring2", "ring3", |
| 38 | "eip"; |
| 39 | clocks = <&cpm_syscon0 1 26>; |
| 40 | }; |
