1Alpine MSIX controller

3See arm,gic-v3.txt for SPI and MSI definitions.

5Required properties:
6
7- compatible: should be "al,alpine-msix"
8- reg: physical base address and size of the registers
9- interrupt-controller: identifies the node as an interrupt controller
10- msi-controller: identifies the node as an PCI Message Signaled Interrupt
11		  controller
12- al,msi-base-spi: SPI base of the MSI frame
13- al,msi-num-spis: number of SPIs assigned to the MSI frame, relative to SPI0
14
15Example:
16
17msix: msix {
18	compatible = "al,alpine-msix";
19	reg = <0x0 0xfbe00000 0x0 0x100000>;
20	interrupt-parent = <&gic>;
21	interrupt-controller;
22	msi-controller;
23	al,msi-base-spi = <160>;
24	al,msi-num-spis = <160>;
25};
