1 * Altera PCIe MSI controller
2
3 Required 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 - interrupts:   specifies the interrupt source of the parent interrupt
11                 controller. The format of the interrupt specifier depends on the
12                 parent interrupt controller.
13 - num-vectors:  number of vectors, range 1 to 32.
14 - msi-controller:       indicates that this is MSI controller node
