1 * ARM Versatile Platform Baseboard PCI interface 2 3 PCI host controller found on the ARM Versatile PB board's FPGA. 4 5 Required 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. 21 22 Example: 23 24 pci-controller@10001000 { 25 compatible = "arm,versatile-pci"; 26 device_type = "pci"; 27 reg = <0x10001000 0x1000 28 0x41000000 0x10000 29 0x42000000 0x100000>; 30 bus-range = <0 0xff>; 31 #address-cells = <3>; 32 #size-cells = <2>; 33 #interrupt-cells = <1>; 34 35 ranges = <0x01000000 0 0x00000000 0x43000000 0 0x00010000 /* downstream I/O */ 36 0x02000000 0 0x50000000 0x50000000 0 0x10000000 /* non-prefetchable memory */ 37 0x42000000 0 0x60000000 0x60000000 0 0x10000000>; /* prefetchable memory */ 38 39 interrupt-map-mask = <0x1800 0 0 7>; 40 interrupt-map = <0x1800 0 0 1 &sic 28 41 0x1800 0 0 2 &sic 29 42 0x1800 0 0 3 &sic 30 43 0x1800 0 0 4 &sic 27 44 45 0x1000 0 0 1 &sic 27 46 0x1000 0 0 2 &sic 28 47 0x1000 0 0 3 &sic 29 48 0x1000 0 0 4 &sic 30 49 50 0x0800 0 0 1 &sic 30 51 0x0800 0 0 2 &sic 27 52 0x0800 0 0 3 &sic 28 53 0x0800 0 0 4 &sic 29 54 55 0x0000 0 0 1 &sic 29 56 0x0000 0 0 2 &sic 30 57 0x0000 0 0 3 &sic 27 58 0x0000 0 0 4 &sic 28>; 59 };
