* 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"
|
|
|
|
