1V3 Semiconductor V360 EPC PCI bridge 2 3This bridge is found in the ARM Integrator/AP (Application Platform) 4 5Required properties: 6- compatible: should be one of: 7 "v3,v360epc-pci" 8 "arm,integrator-ap-pci", "v3,v360epc-pci" 9- reg: should contain two register areas: 10 first the base address of the V3 host bridge controller, 64KB 11 second the configuration area register space, 16MB 12- interrupts: should contain a reference to the V3 error interrupt 13 as routed on the system. 14- bus-range: see pci.txt 15- ranges: this follows the standard PCI bindings in the IEEE Std 16 1275-1994 (see pci.txt) with the following restriction: 17 - The non-prefetchable and prefetchable memory windows must 18 each be exactly 256MB (0x10000000) in size. 19 - The prefetchable memory window must be immediately adjacent 20 to the non-prefetcable memory window 21- dma-ranges: three ranges for the inbound memory region. The ranges must 22 be aligned to a 1MB boundary, and may be 1MB, 2MB, 4MB, 8MB, 16MB, 32MB, 23 64MB, 128MB, 256MB, 512MB, 1GB or 2GB in size. The memory should be marked 24 as pre-fetchable. Two ranges are supported by the hardware. 25 26Integrator-specific required properties: 27- syscon: should contain a link to the syscon device node, since 28 on the Integrator, some registers in the syscon are required to 29 operate the V3 host bridge. 30 31Example: 32 33pci: pciv3@62000000 { 34 compatible = "arm,integrator-ap-pci", "v3,v360epc-pci"; 35 #interrupt-cells = <1>; 36 #size-cells = <2>; 37 #address-cells = <3>; 38 reg = <0x62000000 0x10000>, <0x61000000 0x01000000>; 39 interrupt-parent = <&pic>; 40 interrupts = <17>; /* Bus error IRQ */ 41 clocks = <&pciclk>; 42 bus-range = <0x00 0xff>; 43 ranges = 0x01000000 0 0x00000000 /* I/O space @00000000 */ 44 0x60000000 0 0x01000000 /* 16 MiB @ LB 60000000 */ 45 0x02000000 0 0x40000000 /* non-prefectable memory @40000000 */ 46 0x40000000 0 0x10000000 /* 256 MiB @ LB 40000000 1:1 */ 47 0x42000000 0 0x50000000 /* prefetchable memory @50000000 */ 48 0x50000000 0 0x10000000>; /* 256 MiB @ LB 50000000 1:1 */ 49 dma-ranges = <0x02000000 0 0x20000000 /* EBI memory space */ 50 0x20000000 0 0x20000000 /* 512 MB @ LB 20000000 1:1 */ 51 0x02000000 0 0x80000000 /* Core module alias memory */ 52 0x80000000 0 0x40000000>; /* 1GB @ LB 80000000 */ 53 interrupt-map-mask = <0xf800 0 0 0x7>; 54 interrupt-map = < 55 /* IDSEL 9 */ 56 0x4800 0 0 1 &pic 13 /* INT A on slot 9 is irq 13 */ 57 0x4800 0 0 2 &pic 14 /* INT B on slot 9 is irq 14 */ 58 0x4800 0 0 3 &pic 15 /* INT C on slot 9 is irq 15 */ 59 0x4800 0 0 4 &pic 16 /* INT D on slot 9 is irq 16 */ 60 /* IDSEL 10 */ 61 0x5000 0 0 1 &pic 14 /* INT A on slot 10 is irq 14 */ 62 0x5000 0 0 2 &pic 15 /* INT B on slot 10 is irq 15 */ 63 0x5000 0 0 3 &pic 16 /* INT C on slot 10 is irq 16 */ 64 0x5000 0 0 4 &pic 13 /* INT D on slot 10 is irq 13 */ 65 /* IDSEL 11 */ 66 0x5800 0 0 1 &pic 15 /* INT A on slot 11 is irq 15 */ 67 0x5800 0 0 2 &pic 16 /* INT B on slot 11 is irq 16 */ 68 0x5800 0 0 3 &pic 13 /* INT C on slot 11 is irq 13 */ 69 0x5800 0 0 4 &pic 14 /* INT D on slot 11 is irq 14 */ 70 /* IDSEL 12 */ 71 0x6000 0 0 1 &pic 16 /* INT A on slot 12 is irq 16 */ 72 0x6000 0 0 2 &pic 13 /* INT B on slot 12 is irq 13 */ 73 0x6000 0 0 3 &pic 14 /* INT C on slot 12 is irq 14 */ 74 0x6000 0 0 4 &pic 15 /* INT D on slot 12 is irq 15 */ 75 >; 76};
