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>; }; |
