-* AppliedMicro X-Gene PCIe interface
-
-Required properties:
-- device_type: set to "pci"
-- compatible: should contain "apm,xgene-pcie" to identify the core.
-- reg: A list of physical base address and length for each set of controller
-       registers. Must contain an entry for each entry in the reg-names
-       property.
-- reg-names: Must include the following entries:
-  "csr": controller configuration registers.
-  "cfg": PCIe configuration space registers.
-- #address-cells: set to <3>
-- #size-cells: set to <2>
-- ranges: ranges for the outbound memory, I/O regions.
-- dma-ranges: ranges for the inbound memory regions.
-- #interrupt-cells: set to <1>
-- interrupt-map-mask and interrupt-map: standard PCI properties
-	to define the mapping of the PCIe interface to interrupt
-	numbers.
-- clocks: from common clock binding: handle to pci clock.
-
-Optional properties:
-- status: Either "ok" or "disabled".
-- dma-coherent: Present if DMA operations are coherent
-

-
