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 */
