| 1 | * Broadcom iProc PCIe controller with the platform bus interface | ||
| 2 | |||
| 3 | Required properties: | ||
| 4 | - compatible: Must be "brcm,iproc-pcie" | ||
| 5 | - reg: base address and length of the PCIe controller I/O register space | ||
| 6 | - #interrupt-cells: set to <1> | ||
| 7 | - interrupt-map-mask and interrupt-map, standard PCI properties to define the | ||
| 8 | mapping of the PCIe interface to interrupt numbers | ||
| 9 | - linux,pci-domain: PCI domain ID. Should be unique for each host controller | ||
| 10 | - bus-range: PCI bus numbers covered | ||
| 11 | - #address-cells: set to <3> | ||
| 12 | - #size-cells: set to <2> | ||
| 13 | - device_type: set to "pci" | ||
| 14 | - ranges: ranges for the PCI memory and I/O regions | ||
| 15 | |||
| 16 | Optional properties: | ||
| 17 | - phys: phandle of the PCIe PHY device | ||
| 18 | - phy-names: must be "pcie-phy" | ||
| 19 | |||
