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