  1. * Cadence PCIe endpoint controller
  2.  
  3. Required properties:
  4. - compatible: Should contain "cdns,cdns-pcie-ep" to identify the IP used.
  5. - reg: Should contain the controller register base address and AXI interface
  6.   region base address respectively.
  7. - reg-names: Must be "reg" and "mem" respectively.
  8. - cdns,max-outbound-regions: Set to maximum number of outbound regions
  9.  
  10. Optional properties:
  11. - max-functions: Maximum number of functions that can be configured (default 1).
  12. - phys: From PHY bindings: List of Generic PHY phandles. One per lane if more
  13.   than one in the list.  If only one PHY listed it must manage all lanes.
  14. - phy-names:  List of names to identify the PHY.
  15.  
  16. Example:
  17.  
  18. pcie@fc000000 {
  19.         compatible = "cdns,cdns-pcie-ep";
  20.         reg = <0x0 0xfc000000 0x0 0x01000000>,
  21.               <0x0 0x80000000 0x0 0x40000000>;
  22.         reg-names = "reg", "mem";
  23.         cdns,max-outbound-regions = <16>;
  24.         max-functions = /bits/ 8 <8>;
  25.         phys = <&ep_phy0 &ep_phy1>;
  26.         phy-names = "pcie-lane0","pcie-lane1";
  27. };
