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>;
};
