1 V3 Semiconductor V360 EPC PCI bridge
3 This bridge is found in the ARM Integrator/AP (Application Platform)
6 - compatible: should be one of:
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.
26 Integrator-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.
