* AppliedMicro X-Gene PCIe interface
|
||||
|
||||
Required properties:
|
||||
- device_type: set to "pci"
|
||||
- compatible: should contain "apm,xgene-pcie" to identify the core.
|
||||
- reg: A list of physical base address and length for each set of controller
|
||||
registers. Must contain an entry for each entry in the reg-names
|
||||
property.
|
||||
- reg-names: Must include the following entries:
|
||||
"csr": controller configuration registers.
|
||||
"cfg": PCIe configuration space registers.
|
||||
- #address-cells: set to <3>
|
||||
- #size-cells: set to <2>
|
||||
- ranges: ranges for the outbound memory, I/O regions.
|
||||
- dma-ranges: ranges for the inbound memory 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.
|
||||
- clocks: from common clock binding: handle to pci clock.
|
||||
|
||||
Optional properties:
|
||||
- status: Either "ok" or "disabled".
|
||||
- dma-coherent: Present if DMA operations are coherent
|
||||
|
||||
Example:
|
||||
|
||||
pcie0: pcie@1f2b0000 {
|
||||
status = "disabled";
|
||||
device_type = "pci";
|
||||
compatible = "apm,xgene-storm-pcie", "apm,xgene-pcie";

#size-cells = <2>;

#address-cells = <3>;
