| 2 | |
| 3 | Required properties: |
| 4 | - compatible: should contain "altr,msi-1.0" |
| 5 | - reg: specifies the physical base address of the controller and |
| 6 | the length of the memory mapped region. |
| 7 | - reg-names: must include the following entries: |
| 8 | "csr": CSR registers |
| 9 | "vector_slave": vectors slave port region |
| 10 | - interrupts: specifies the interrupt source of the parent interrupt |
| 11 | controller. The format of the interrupt specifier depends on the |
| 12 | parent interrupt controller. |
| 13 | - num-vectors: number of vectors, range 1 to 32. |
| 14 | - msi-controller: indicates that this is MSI controller node |
| 15 | |

| 17 | Example |
| 18 | msi0: msi@0xFF200000 { |
| 19 | compatible = "altr,msi-1.0"; |
| 20 | reg = <0xFF200000 0x00000010 |
| 21 | 0xFF200010 0x00000080>; |
| 22 | reg-names = "csr", "vector_slave"; |
| 23 | interrupt-parent = <&hps_0_arm_gic_0>; |
| 24 | interrupts = <0 42 4>; |
| 25 | msi-controller; |
| 26 | num-vectors = <32>; |
| 27 | }; |
