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- 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 16 17Example 18msi0: 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}; 28
