Alpine MSIX controller See arm,gic-v3.txt for SPI and MSI definitions. Required properties: - compatible: should be "al,alpine-msix" - reg: physical base address and size of the registers - 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, relative to SPI0 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>; };
