+* Broadcom iProc PCIe controller with the platform bus interface
+
+Required properties:
+- compatible: Must be "brcm,iproc-pcie"
+- reg: base address and length of the PCIe controller I/O register space
+- #interrupt-cells: set to <1>
+- interrupt-map-mask and interrupt-map, standard PCI properties to define the
+  mapping of the PCIe interface to interrupt numbers
+- linux,pci-domain: PCI domain ID. Should be unique for each host controller
+- bus-range: PCI bus numbers covered
+- #address-cells: set to <3>
+- #size-cells: set to <2>
+- device_type: set to "pci"
+- ranges: ranges for the PCI memory and I/O regions
+
+Optional properties:
+- phys: phandle of the PCIe PHY device
+- phy-names: must be "pcie-phy"
+
