Required properties:

- compatible: Should contain "cdns,cdns-pcie-ep" to identify the IP used.

- reg: Should contain the controller register base address and AXI interface

  region base address respectively.

- reg-names: Must be "reg" and "mem" respectively.

- cdns,max-outbound-regions: Set to maximum number of outbound regions



Optional properties:

- max-functions: Maximum number of functions that can be configured (default 1).



Example:



pcie@fc000000 {

	compatible = "cdns,cdns-pcie-ep";

	reg = <0x0 0xfc000000 0x0 0x01000000>,

	      <0x0 0x80000000 0x0 0x40000000>;

	reg-names = "reg", "mem";

	cdns,max-outbound-regions = <16>;

	max-functions = /bits/ 8 <8>;

};
