1 Aardvark PCIe controller
3 This PCIe controller is used on the Marvell Armada 3700 ARM64 SoC.
5 The Device Tree node describing an Aardvark PCIe controller must
6 contain the following properties:
8 - compatible: Should be "marvell,armada-3700-pcie"
9 - reg: range of registers for the PCIe controller
10 - interrupts: the interrupt line of the PCIe controller
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 - msi-controller: indicates that the PCIe controller can itself
18 - msi-parent: pointer to the MSI controller to be used
19 - interrupt-map-mask and interrupt-map: standard PCI properties to
20 define the mapping of the PCIe interface to interrupt numbers.
21 - bus-range: PCI bus numbers covered
23 In addition, the Device Tree describing an Aardvark PCIe controller
24 must include a sub-node that describes the legacy interrupt controller
25 built into the PCIe controller. This sub-node must have the following
28 - interrupt-controller
29 - #interrupt-cells: set to <1>
