1* Altera PCIe MSI controller 2 3Required 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- interrupt-parent: interrupt source phandle. 11- interrupts: specifies the interrupt source of the parent interrupt 12 controller. The format of the interrupt specifier depends on the 13 parent interrupt controller. 14- num-vectors: number of vectors, range 1 to 32. 15- msi-controller: indicates that this is MSI controller node 16 17 18Example 19msi0: msi@0xFF200000 { 20 compatible = "altr,msi-1.0"; 21 reg = <0xFF200000 0x00000010 22 0xFF200010 0x00000080>; 23 reg-names = "csr", "vector_slave"; 24 interrupt-parent = <&hps_0_arm_gic_0>; 25 interrupts = <0 42 4>; 26 msi-controller; 27 num-vectors = <32>; 28}; 29
