- * 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
- 0x1800 0 0 2 &sic 29
- 0x1800 0 0 3 &sic 30
- 0x1800 0 0 4 &sic 27
- 0x1000 0 0 1 &sic 27
- 0x1000 0 0 2 &sic 28
- 0x1000 0 0 3 &sic 29
- 0x1000 0 0 4 &sic 30
- 0x0800 0 0 1 &sic 30
- 0x0800 0 0 2 &sic 27
- 0x0800 0 0 3 &sic 28
- 0x0800 0 0 4 &sic 29
- 0x0000 0 0 1 &sic 29
- 0x0000 0 0 2 &sic 30
- 0x0000 0 0 3 &sic 27
