1 * Xilinx NWL PCIe Root Port Bridge DT description
4 - compatible: Should contain "xlnx,nwl-pcie-2.11"
5 - #address-cells: Address representation for root ports, set to <3>
6 - #size-cells: Size representation for root ports, set to <2>
7 - #interrupt-cells: specifies the number of cells needed to encode an
8 interrupt source. The value must be 1.
9 - reg: Should contain Bridge, PCIe Controller registers location,
10 configuration space, and length
11 - reg-names: Must include the following entries:
12 "breg": bridge registers
13 "pcireg": PCIe controller registers
14 "cfg": configuration space region
15 - device_type: must be "pci"
16 - interrupts: Should contain NWL PCIe interrupt
17 - interrupt-names: Must include the following entries:
18 "msi1, msi0": interrupt asserted when MSI is received
19 "intx": interrupt asserted when a legacy interrupt is received
20 "misc": interrupt asserted when miscellaneous is received
21 - interrupt-map-mask and interrupt-map: standard PCI properties to define the
22 mapping of the PCI interface to interrupt numbers.
23 - ranges: ranges for the PCI memory regions (I/O space region is not
24 supported by hardware)
25 Please refer to the standard PCI bus binding document for a more
27 - msi-controller: indicates that this is MSI controller node
28 - msi-parent: MSI parent of the root complex itself
29 - legacy-interrupt-controller: Interrupt controller device node for Legacy interrupts
30 - interrupt-controller: identifies the node as an interrupt controller
31 - #interrupt-cells: should be set to 1
32 - #address-cells: specifies the number of cells needed to encode an
33 address. The value must be 0.
