31 - phys: List of PHY specifiers (used by generic PHY framework).
32 - phy-names : Must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the
33 number of PHYs as specified in *phys* property.
34 - power-domains: A phandle and power domain specifier pair to the power domain
35 which is responsible for collapsing and restoring power to the peripheral.
36 - bus-range: Range of bus numbers associated with this controller.
37 - ranges: Ranges for the PCI memory and I/O regions.
39 Required properties for MT7623/MT2701:
40 - #interrupt-cells: Size representation for interrupts (must be 1)
41 - interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
42 Please refer to the standard PCI bus binding document for a more detailed
44 - resets: Must contain an entry for each entry in reset-names.
45 See ../reset/reset.txt for details.
46 - reset-names: Must be "pcie-rst0", "pcie-rst1", "pcie-rstN".. based on the
49 Required properties for MT2712/MT7622:
50 -interrupts: A list of interrupt outputs of the controller, must have one
51 entry for each PCIe port
53 In addition, the device tree node must have sub-nodes describing each
54 PCIe port interface, having the following mandatory properties:
57 - device_type: Must be "pci"
58 - reg: Only the first four bytes are used to refer to the correct bus number
60 - #address-cells: Must be 3
61 - #size-cells: Must be 2
62 - #interrupt-cells: Must be 1
63 - interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
64 Please refer to the standard PCI bus binding document for a more detailed
66 - ranges: Sub-ranges distributed from the PCIe controller node. An empty
67 property is sufficient.
68 - num-lanes: Number of lanes to use for this port.
