1* Marvell Armada 7K/8K PCIe interface
2
3This PCIe host controller is based on the Synopsys DesignWare PCIe IP
4and thus inherits all the common properties defined in designware-pcie.txt.
5
6Required properties:
7- compatible: "marvell,armada8k-pcie"
8- reg: must contain two register regions
9   - the control register region
10   - the config space region
11- reg-names:
12   - "ctrl" for the control register region
13   - "config" for the config space region
14- interrupts: Interrupt specifier for the PCIe controller
15- clocks: reference to the PCIe controller clocks
16- clock-names: mandatory if there is a second clock, in this case the
17   name must be "core" for the first clock and "reg" for the second
18   one
19
20Optional properties:
21- phys: phandle(s) to PHY node(s) following the generic PHY bindings.
22	Either 1, 2 or 4 PHYs might be needed depending on the number of
23	PCIe lanes.
24- phy-names: names of the PHYs corresponding to the number of lanes.
25	Must be "cp0-pcie0-x4-lane0-phy", "cp0-pcie0-x4-lane1-phy" for
26	2 PHYs.
