5*4882a593SmuzhiyunRequired properties:
6*4882a593Smuzhiyun
7*4882a593Smuzhiyun- compatible: should be "al,alpine-msix"
8*4882a593Smuzhiyun- reg: physical base address and size of the registers
9*4882a593Smuzhiyun- interrupt-controller: identifies the node as an interrupt controller
10*4882a593Smuzhiyun- msi-controller: identifies the node as an PCI Message Signaled Interrupt
11*4882a593Smuzhiyun		  controller
12*4882a593Smuzhiyun- al,msi-base-spi: SPI base of the MSI frame
13*4882a593Smuzhiyun- al,msi-num-spis: number of SPIs assigned to the MSI frame, relative to SPI0
