-* 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";
- reg = <0x10001000 0x1000
- 0x41000000 0x10000
- 0x42000000 0x100000>;
- bus-range = <0 0xff>;
- #address-cells = <3>;
- #size-cells = <2>;
- #interrupt-cells = <1>;
-
- ranges = <0x01000000 0 0x00000000 0x43000000 0 0x00010000 /* downstream I/O */
- 0x02000000 0 0x50000000 0x50000000 0 0x10000000 /* non-prefetchable memory */
- 0x42000000 0 0x60000000 0x60000000 0 0x10000000>; /* prefetchable memory */
-
- interrupt-map-mask = <0x1800 0 0 7>;
