1 * Cadence PCIe host controller
3 This PCIe controller inherits the base properties defined in
7 - compatible: Should contain "cdns,cdns-pcie-host" to identify the IP used.
8 - reg: Should contain the controller register base address, PCIe configuration
9 window base address, and AXI interface region base address respectively.
10 - reg-names: Must be "reg", "cfg" and "mem" respectively.
11 - #address-cells: Set to <3>
12 - #size-cells: Set to <2>
13 - device_type: Set to "pci"
14 - ranges: Ranges for the PCI memory and I/O regions
15 - #interrupt-cells: Set to <1>
16 - interrupt-map-mask and interrupt-map: Standard PCI properties to define the
17 mapping of the PCIe interface to interrupt numbers.
20 - cdns,max-outbound-regions: Set to maximum number of outbound regions
22 - cdns,no-bar-match-nbits: Set into the no BAR match register to configure the
23 number of least significant bits kept during inbound (PCIe -> AXI) address
24 translations (default 32)
25 - vendor-id: The PCI vendor ID (16 bits, default is design dependent)
26 - device-id: The PCI device ID (16 bits, default is design dependent)
27 - phys: From PHY bindings: List of Generic PHY phandles. One per lane if more
28 than one in the list. If only one PHY listed it must manage all lanes.
29 - phy-names: List of names to identify the PHY.
