+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-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, 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>;
+};
