1* ARM Versatile Platform Baseboard PCI interface
2
3PCI host controller found on the ARM Versatile PB board's FPGA.
4
5Required properties:
6- compatible: should contain "arm,versatile-pci" to identify the Versatile PCI
7  controller.
8- reg: base addresses and lengths of the pci controller. There must be 3
9  entries:
10	- Versatile-specific registers
11	- Self Config space
12	- Config space
13- #address-cells: set to <3>
14- #size-cells: set to <2>
15- device_type: set to "pci"
16- bus-range: set to <0 0xff>
17- ranges: ranges for the PCI memory and I/O regions
18- #interrupt-cells: set to <1>
19- interrupt-map-mask and interrupt-map: standard PCI properties to define
20	the mapping of the PCI interface to interrupt numbers.
