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>;

};
