| * 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 |
| - 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" |
| |
| Optional properties: |
| - reset-gpio: gpio pin number of power good signal |
