* Marvell Armada 7K/8K PCIe interface
|
||
|
|
|
||
|
|
This PCIe host controller is based on the Synopsys DesignWare PCIe IP
|
||
|
|
and thus inherits all the common properties defined in designware-pcie.txt.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "marvell,armada8k-pcie"
|
||
|
|
- reg: must contain two register regions
|
||
|
|
- the control register region
|
||
|
|
- the config space region
|
||
|
|
- reg-names:
|
||
|
|
- "ctrl" for the control register region
|
||
|
|
- "config" for the config space region
|
||
|
|
- interrupts: Interrupt specifier for the PCIe controller
|
||
|
|
- clocks: reference to the PCIe controller clocks
|
||
|
|
- clock-names: mandatory if there is a second clock, in this case the
|
||
|
|
name must be "core" for the first clock and "reg" for the second
|
||
|
|
one
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- phys: phandle(s) to PHY node(s) following the generic PHY bindings.
|
||
|
|
Either 1, 2 or 4 PHYs might be needed depending on the number of
|
||
|
|
PCIe lanes.
|
||
|
|
- phy-names: names of the PHYs corresponding to the number of lanes.
|
||
|
|
Must be "cp0-pcie0-x4-lane0-phy", "cp0-pcie0-x4-lane1-phy" for
|
||
|
|
2 PHYs.
|
||
|
|
