| 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 */ |
| 30 | }; |
