    +Alpine MSIX controller
    +
    +Required properties:
    +
    +- compatible: should be "al,alpine-msix"
    +- reg: physical base address and size of the registers
    +- interrupt-parent: specifies the parent interrupt controller.
    +- interrupt-controller: identifies the node as an interrupt controller
    +- msi-controller: identifies the node as an PCI Message Signaled Interrupt
    + controller
    +- al,msi-base-spi: SPI base of the MSI frame
    +- al,msi-num-spis: number of SPIs assigned to the MSI frame
    +
    +Example:
    +
    +msix: msix {
    + compatible = "al,alpine-msix";
    + reg = <0x0 0xfbe00000 0x0 0x100000>;
    + interrupt-parent = <&gic>;
    + interrupt-controller;
    + msi-controller;
    + al,msi-base-spi = <160>;
    + al,msi-num-spis = <160>;
    +};
