* 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>;
