| 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. |
| - #interrupt-cells: Size representation for interrupts (must be 1) |
| - interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties |
| Please refer to the standard PCI bus binding document for a more detailed |
| explanation. |
| - clocks: Must contain an entry for each entry in clock-names. |
| See ../clocks/clock-bindings.txt for details. |

| - pex |
| - afi |

| - pinctrl-names: A list of pinctrl state names. Must contain the following |
| entries: |
| - "default": active state, puts PCIe I/O out of deep power down state |
| - "idle": puts PCIe I/O into deep power down state |
| - pinctrl-0: phandle for the default/active state of pin configurations. |
| - pinctrl-1: phandle for the idle state of pin configurations. |
| |
| Required properties on Tegra124 and later (deprecated): |
| - phys: Must contain an entry for each entry in phy-names. |
| - phy-names: Must include the following entries: |
| - pcie |
| |
| These properties are deprecated in favour of per-lane PHYs define in each of |
| the root ports (see below). |

| property is sufficient. |

| 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. |

| of entries does not have to (though usually will) be equal to the specified |

| 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). |
