* 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"



Example:

	pcie0: pcie@18012000 {

		compatible = "brcm,iproc-pcie";

		reg = <0x18012000 0x1000>;



		#interrupt-cells = <1>;

		interrupt-map-mask = <0 0 0 0>;

		interrupt-map = <0 0 0 0 &gic GIC_SPI 100 IRQ_TYPE_NONE>;



		linux,pci-domain = <0>;



		bus-range = <0x00 0xff>;



		#address-cells = <3>;

		#size-cells = <2>;

		device_type = "pci";

		ranges = <0x81000000 0 0	  0x28000000 0 0x00010000

			  0x82000000 0 0x20000000 0x20000000 0 0x04000000>;



		phys = <&phy 0 5>;

		phy-names = "pcie-phy";

	};



	pcie1: pcie@18013000 {

		compatible = "brcm,iproc-pcie";

		reg = <0x18013000 0x1000>;



		#interrupt-cells = <1>;

		interrupt-map-mask = <0 0 0 0>;

		interrupt-map = <0 0 0 0 &gic GIC_SPI 106 IRQ_TYPE_NONE>;



		linux,pci-domain = <1>;



		bus-range = <0x00 0xff>;



		#address-cells = <3>;

		#size-cells = <2>;

		device_type = "pci";

		ranges = <0x81000000 0 0	  0x48000000 0 0x00010000

			  0x82000000 0 0x40000000 0x40000000 0 0x04000000>;



		phys = <&phy 1 6>;

		phy-names = "pcie-phy";

	};
