1 * AppliedMicro X-Gene v1 PCIe MSI controller
5 - compatible: should be "apm,xgene1-msi" to identify
6 	      X-Gene v1 PCIe MSI controller block.
7 - msi-controller: indicates that this is an X-Gene v1 PCIe MSI controller node
8 - reg: physical base address (0x79000000) and length (0x900000) for controller
11 - reg-names: not required
12 - interrupts: A list of 16 interrupt outputs of the controller, starting from
