1 * Altera PCIe controller
4 - compatible : should contain "altr,pcie-root-port-1.0" or "altr,pcie-root-port-2.0"
5 - reg: a list of physical base address and length for TXS and CRA.
6 For "altr,pcie-root-port-2.0", additional HIP base address and length.
7 - reg-names: must include the following entries:
8 "Txs": TX slave port region
9 "Cra": Control register access region
10 "Hip": Hard IP region (if "altr,pcie-root-port-2.0")
11 - interrupts: specifies the interrupt source of the parent interrupt
12 controller. The format of the interrupt specifier depends
13 on the parent interrupt controller.
14 - device_type: must be "pci"
15 - #address-cells: set to <3>
16 - #size-cells: set to <2>
17 - #interrupt-cells: set to <1>
18 - ranges: describes the translation of addresses for root ports and
20 - interrupt-map-mask and interrupt-map: standard PCI properties to define the
21 mapping of the PCIe interface to interrupt numbers.
24 - msi-parent: Link to the hardware entity that serves as the MSI controller
25 for this PCIe controller.
26 - bus-range: PCI bus numbers covered
