1 | * ThunderX PCI host controller for pass-1.x silicon |
2 | ||
3 | Firmware-initialized PCI host controller to on-chip devices found on | |
4 | some Cavium ThunderX processors. These devices have ECAM-based config | |
5 | access, but the BARs are all at fixed addresses. We handle the fixed | |
6 | addresses by synthesizing Enhanced Allocation (EA) capabilities for | |
7 | these devices. | |
8 | ||
9 | The properties and their meanings are identical to those described in | |
10 | host-generic-pci.txt except as listed below. | |
11 | ||
12 | Properties of the host controller node that differ from | |
13 | host-generic-pci.txt: | |
14 | ||
15 | - compatible : Must be "cavium,pci-host-thunder-ecam" | |
16 | ||
17 | Example: | |
18 | ||
19 | pcie@84b000000000 { | |
20 | compatible = "cavium,pci-host-thunder-ecam"; | |
21 | device_type = "pci"; | |
22 | msi-parent = <&its>; | |
23 | msi-map = <0 &its 0x30000 0x10000>; | |
24 | bus-range = <0 31>; | |
25 | #size-cells = <2>; | |
26 | #address-cells = <3>; | |
27 | #stream-id-cells = <1>; | |
28 | reg = <0x84b0 0x00000000 0 0x02000000>; /* Configuration space */ | |
29 | ranges = <0x03000000 0x8180 0x00000000 0x8180 0x00000000 0x80 0x00000000>; /* mem ranges */ | |
