* ARM Versatile Platform Baseboard PCI interface
|
|
|
|
PCI host controller found on the ARM Versatile PB board's FPGA.
|
|
|
|
Required properties:
|
|
- compatible: should contain "arm,versatile-pci" to identify the Versatile PCI
|
|
controller.
|
|
- reg: base addresses and lengths of the PCI controller. There must be 3
|
|
entries:
|
|
- Versatile-specific registers
|
|
- Self Config space
|
|
- Config space
|
|
- #address-cells: set to <3>
|
|
- #size-cells: set to <2>
|
|
- device_type: set to "pci"
|
|
- bus-range: set to <0 0xff>
|
|
- ranges: ranges for the PCI memory and I/O regions
|
|
- #interrupt-cells: set to <1>
|
|
- interrupt-map-mask and interrupt-map: standard PCI properties to define
|
|
the mapping of the PCI interface to interrupt numbers.
|
|
|
|
Example:
|
|
|
|
pci-controller@10001000 {
|
|
compatible = "arm,versatile-pci";
|
|
device_type = "pci";

|
|
bus-range = <0 0xff>;
