1NVIDIA Tegra PCIe controller
2
3Required properties:
4- compatible: Must be:
5 - "nvidia,tegra20-pcie": for Tegra20
6 - "nvidia,tegra30-pcie": for Tegra30
7 - "nvidia,tegra124-pcie": for Tegra124 and Tegra132
8 - "nvidia,tegra210-pcie": for Tegra210
9 - "nvidia,tegra186-pcie": for Tegra186
10- power-domains: To ungate power partition by BPMP powergate driver. Must
11 contain BPMP phandle and PCIe power partition ID. This is required only
12 for Tegra186.
13- device_type: Must be "pci"
14- reg: A list of physical base address and length for each set of controller
15 registers. Must contain an entry for each entry in the reg-names property.
16- reg-names: Must include the following entries:
17 "pads": PADS registers
18 "afi": AFI registers
19 "cs": configuration space region
20- interrupts: A list of interrupt outputs of the controller. Must contain an
21 entry for each entry in the interrupt-names property.
22- interrupt-names: Must include the following entries:
23 "intr": The Tegra interrupt that is asserted for controller interrupts
24 "msi": The Tegra interrupt that is asserted when an MSI is received
25- bus-range: Range of bus numbers associated with this controller
26- #address-cells: Address representation for root ports (must be 3)
27 - cell 0 specifies the bus and device numbers of the root port:
28 [23:16]: bus number
29 [15:11]: device number
30 - cell 1 denotes the upper 32 address bits and should be 0
31 - cell 2 contains the lower 32 address bits and is used to translate to the
32 CPU address space
33- #size-cells: Size representation for root ports (must be 2)
34- ranges: Describes the translation of addresses for root ports and standard
35 PCI regions. The entries must be 6 cells each, where the first three cells
36 correspond to the address as described for the #address-cells property
37 above, the fourth cell is the physical CPU address to translate to and the
38 fifth and six cells are as described for the #size-cells property above.
39 - The first two entries are expected to translate the addresses for the root
40 port registers, which are referenced by the assigned-addresses property of
41 the root port nodes (see below).
42 - The remaining entries setup the mapping for the standard I/O, memory and
43 prefetchable PCI regions. The first cell determines the type of region
44 that is setup:
45 - 0x81000000: I/O memory region
46 - 0x82000000: non-prefetchable memory region
47 - 0xc2000000: prefetchable memory region
48 Please refer to the standard PCI bus binding document for a more detailed
49 explanation.
50- #interrupt-cells: Size representation for interrupts (must be 1)
51- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
52 Please refer to the standard PCI bus binding document for a more detailed
53 explanation.
54- clocks: Must contain an entry for each entry in clock-names.
55 See ../clocks/clock-bindings.txt for details.
56- clock-names: Must include the following entries:

64 - pex
65 - afi
66 - pcie_x
67
68Optional properties:
69- pinctrl-names: A list of pinctrl state names. Must contain the following
70 entries:
71 - "default": active state, puts PCIe I/O out of deep power down state
72 - "idle": puts PCIe I/O into deep power down state
73- pinctrl-0: phandle for the default/active state of pin configurations.
74- pinctrl-1: phandle for the idle state of pin configurations.

77- phys: Must contain an entry for each entry in phy-names.
78- phy-names: Must include the following entries:
79 - pcie

269Note that devices on the PCI bus are dynamically discovered using PCI's bus
270enumeration and therefore don't need corresponding device nodes in DT. However
271if a device on the PCI bus provides a non-probeable bus such as I2C or SPI,
272device nodes need to be added in order to allow the bus' children to be
273instantiated at the proper location in the operating system's device tree (as
274illustrated by the optional nodes in the example above).
