-NVIDIA Tegra PCIe controller
-
-Required properties:
-- compatible: Must be:
-  - "nvidia,tegra20-pcie": for Tegra20
-  - "nvidia,tegra30-pcie": for Tegra30
-  - "nvidia,tegra124-pcie": for Tegra124 and Tegra132
-  - "nvidia,tegra210-pcie": for Tegra210
-  - "nvidia,tegra186-pcie": for Tegra186
-- power-domains: To ungate power partition by BPMP powergate driver. Must
-  contain BPMP phandle and PCIe power partition ID. This is required only
-  for Tegra186.
-- device_type: Must be "pci"
-- reg: A list of physical base address and length for each set of controller
-  registers. Must contain an entry for each entry in the reg-names property.
-- reg-names: Must include the following entries:
-  "pads": PADS registers
-  "afi": AFI registers
-  "cs": configuration space region
-- interrupts: A list of interrupt outputs of the controller. Must contain an
-  entry for each entry in the interrupt-names property.
-- interrupt-names: Must include the following entries:
-  "intr": The Tegra interrupt that is asserted for controller interrupts
-  "msi": The Tegra interrupt that is asserted when an MSI is received
-- bus-range: Range of bus numbers associated with this controller
-- #address-cells: Address representation for root ports (must be 3)
-  - cell 0 specifies the bus and device numbers of the root port:
-    [23:16]: bus number
-    [15:11]: device number
-  - cell 1 denotes the upper 32 address bits and should be 0
-  - cell 2 contains the lower 32 address bits and is used to translate to the
-    CPU address space
-- #size-cells: Size representation for root ports (must be 2)
-- ranges: Describes the translation of addresses for root ports and standard
-  PCI regions. The entries must be 6 cells each, where the first three cells
-  correspond to the address as described for the #address-cells property
-  above, the fourth cell is the physical CPU address to translate to and the
-  fifth and six cells are as described for the #size-cells property above.
-  - The first two entries are expected to translate the addresses for the root
-    port registers, which are referenced by the assigned-addresses property of
-    the root port nodes (see below).
-  - The remaining entries setup the mapping for the standard I/O, memory and
-    prefetchable PCI regions. The first cell determines the type of region
-    that is setup:
-    - 0x81000000: I/O memory region
-    - 0x82000000: non-prefetchable memory region
-    - 0xc2000000: prefetchable memory region
-  Please refer to the standard PCI bus binding document for a more detailed
-  explanation.

-  Please refer to the standard PCI bus binding document for a more detailed
-  explanation.

-Root ports are defined as subnodes of the PCIe controller node.
-
-Required properties:
-- device_type: Must be "pci"
-- assigned-addresses: Address and size of the port configuration registers
-- reg: PCI bus address of the root port
-- #address-cells: Must be 3
-- #size-cells: Must be 2
-- ranges: Sub-ranges distributed from the PCIe controller node. An empty
-  property is sufficient.
-- nvidia,num-lanes: Number of lanes to use for this port. Valid combinations
-  are:
-  - Root port 0 uses 4 lanes, root port 1 is unused.
-  - Both root ports use 2 lanes.
-
-Required properties for Tegra124 and later:
-- phys: Must contain an phandle to a PHY for each entry in phy-names.
-- phy-names: Must include an entry for each active lane. Note that the number
-  of entries does not have to (though usually will) be equal to the specified
-  number of lanes in the nvidia,num-lanes property. Entries are of the form
-  "pcie-N": where N ranges from 0 to the value specified in nvidia,num-lanes.

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

+      DT. However if a device on the PCI bus provides a non-probeable bus such
+      as I2C or SPI, device nodes need to be added in order to allow the bus'
+      children to be instantiated at the proper location in the operating
+      system's device tree (as illustrated by the optional nodes in the
