+PCI Endpoint Function Bus
+
+This describes the bindings for endpoint function bus to which endpoint
+function devices should be attached.
+
+Required Properties:
+ - compatible: Should be "pci-epf-bus"
+
+One or more subnodes representing PCIe endpoint function device exposed
+to the remote host.
+
+Example:
+Following is an example of NTB device exposed to the remote host.
+
+epf_bus {
+ compatible = "pci-epf-bus";
+
+ ntb {
+ compatible = "pci-epf-ntb";
+ epcs = <&pcie0_ep>, <&pcie1_ep>;
+ epc-names = "primary", "secondary";
+ vendor-id = /bits/ 16 <0x104c>;
+ device-id = /bits/ 16 <0xb00d>;
+ num-mws = <4>;
+ mws-size = <0x100000>, <0x100000>, <0x100000>, <0x100000>;
+ };
+};
