- * Synopsys Designware PCIe interface
- Required properties:
- - compatible: should contain "snps,dw-pcie" to identify the core.
- - reg: Should contain the configuration address space.
- - reg-names: Must be "config" for the PCIe configuration space.
- (The old way of getting the configuration address space from "ranges"
- is deprecated and should be avoided.)
- - #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
- - #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.
- - num-lanes: number of lanes to use
- Optional properties:
- - num-lanes: number of lanes to use (this property should be specified unless
- the link is brought already up in BIOS)
- - reset-gpio: gpio pin number of power good signal
- - bus-range: PCI bus numbers covered (it is recommended for new devicetrees to
- specify this property, to keep backwards compatibility a range of 0x00-0xff
- is assumed if not present)
- - clocks: Must contain an entry for each entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
- - clock-names: Must include the following entries:
- - "pcie"
- - "pcie_bus"
