| * Altera PCIe MSI controller |
| |
| Required properties: |
| - compatible: should contain "altr,msi-1.0" |
| - reg: specifies the physical base address of the controller and |
| the length of the memory mapped region. |
| - reg-names: must include the following entries: |
| "csr": CSR registers |
| "vector_slave": vectors slave port region |
| - interrupts: specifies the interrupt source of the parent interrupt |
| controller. The format of the interrupt specifier depends on the |
| parent interrupt controller. |
| - num-vectors: number of vectors, range 1 to 32. |
| - msi-controller: indicates that this is MSI controller node |
| |
| |
| Example |
| msi0: msi@0xFF200000 { |
| compatible = "altr,msi-1.0"; |
| reg = <0xFF200000 0x00000010 |
| 0xFF200010 0x00000080>; |
| reg-names = "csr", "vector_slave"; |
| interrupt-parent = <&hps_0_arm_gic_0>; |
| interrupts = <0 42 4>; |
| msi-controller; |
| num-vectors = <32>; |
| }; |
