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