-- reg: base addresses and lengths of the pcie controller,
-       the phy controller, additional register for the phy controller.
-- interrupts: interrupt values for level interrupt,
-       pulse interrupt, special interrupt.
-- clocks: from common clock binding: handle to pci clock.
-- clock-names: from common clock binding: should be "pcie" and "pcie_bus".
+- compatible: should contain "snps,dw-pcie" to identify the core.
