-* Broadcom iProc PCIe controller with the platform bus interface
-
-Required properties:
-- compatible:
-      "brcm,iproc-pcie" for the first generation of PAXB based controller,
-used in SoCs including NSP, Cygnus, NS2, and Pegasus
-      "brcm,iproc-pcie-paxb-v2" for the second generation of PAXB-based
-controllers, used in Stingray
-      "brcm,iproc-pcie-paxc" for the first generation of PAXC based
-controller, used in NS2
-      "brcm,iproc-pcie-paxc-v2" for the second generation of PAXC based
-controller, used in Stingray
-  PAXB-based root complex is used for external endpoint devices. PAXC-based
-root complex is connected to emulated endpoint devices internal to the ASIC
-- 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"
-- dma-coherent: present if DMA operations are coherent
-- dma-ranges: Some PAXB-based root complexes do not have inbound mapping done
-  by the ASIC after power on reset.  In this case, SW is required to configure
-the mapping, based on inbound memory regions specified by this property.
-
-- brcm,pcie-ob: Some iProc SoCs do not have the outbound address mapping done
-by the ASIC after power on reset. In this case, SW needs to configure it
-
-If the brcm,pcie-ob property is present, the following properties become
-effective:
-
-Required:
-- brcm,pcie-ob-axi-offset: The offset from the AXI address to the internal
-address used by the iProc PCIe core (not the PCIe address)
-
-MSI support (optional):
-
-For older platforms without MSI integrated in the GIC, iProc PCIe core provides
-an event queue based MSI support.  The iProc MSI uses host memories to store
-MSI posted writes in the event queues
-
-On newer iProc platforms, gicv2m or gicv3-its based MSI support should be used
-
-- msi-map: Maps a Requester ID to an MSI controller and associated MSI
-sideband data
-
-- msi-parent: Link to the device node of the MSI controller, used when no MSI
-sideband data is passed between the iProc PCIe controller and the MSI
-controller
-
-Refer to the following binding documents for more detailed description on
-the use of 'msi-map' and 'msi-parent':
-  Documentation/devicetree/bindings/pci/pci-msi.txt
-  Documentation/devicetree/bindings/interrupt-controller/msi.txt
-
-When the iProc event queue based MSI is used, one needs to define the
-following properties in the MSI device node:
-- compatible: Must be "brcm,iproc-msi"
-- msi-controller: claims itself as an MSI controller
-- interrupts: List of interrupt IDs from its parent interrupt device
-
-Optional properties:
-- brcm,pcie-msi-inten: Needs to be present for some older iProc platforms that
-require the interrupt enable registers to be set explicitly to enable MSI
-
-Example:
-	pcie0: pcie@18012000 {
-		compatible = "brcm,iproc-pcie";
-		reg = <0x18012000 0x1000>;
