* 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>;
interrupt-map = <0x1800 0 0 1 &sic 28
