1* Altera PCIe MSI controller
2
3Required properties:
4- compatible:	should contain "altr,msi-1.0"
5- reg:		specifies the physical base address of the controller and
6		the length of the memory mapped region.
7- reg-names:	must include the following entries:
8		"csr": CSR registers
9		"vector_slave": vectors slave port region
10- interrupt-parent:	interrupt source phandle.
11- interrupts:	specifies the interrupt source of the parent interrupt
12		controller. The format of the interrupt specifier depends on the
13		parent interrupt controller.
14- num-vectors:	number of vectors, range 1 to 32.
15- msi-controller:	indicates that this is MSI controller node
