-	"snps,dw-pcie-ep" for EP mode;
-- reg: For designware cores version < 4.80 contains the configuration
-       address space. For designware core version >= 4.80, contains
-       the configuration and ATU address space
-- reg-names: Must be "config" for the PCIe configuration space and "atu" for
-	     the ATU address space.
-    (The old way of getting the configuration address space from "ranges"
-    is deprecated and should be avoided.)
-RC mode:
-- #address-cells: set to <3>
-- #size-cells: set to <2>
-- device_type: set to "pci"
-- ranges: ranges for the PCI memory and I/O regions
-- #interrupt-cells: set to <1>
-- interrupt-map-mask and interrupt-map: standard PCI
-	properties to define the mapping of the PCIe interface to interrupt
-	numbers.
-EP mode:
-- num-ib-windows: number of inbound address translation windows
-- num-ob-windows: number of outbound address translation windows
-
-Optional properties:
-- num-lanes: number of lanes to use (this property should be specified unless
-  the link is brought already up in BIOS)
-- reset-gpio: GPIO pin number of power good signal
-- clocks: Must contain an entry for each entry in clock-names.
-	See ../clocks/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
-	- "pcie"
-	- "pcie_bus"
-- snps,enable-cdm-check: This is a boolean property and if present enables
-   automatic checking of CDM (Configuration Dependent Module) registers
-   for data corruption. CDM registers include standard PCIe configuration
-   space registers, Port Logic registers, DMA and iATU (internal Address
-   Translation Unit) registers.
-RC mode:
-- num-viewport: number of view ports configured in hardware. If a platform
-  does not specify it, the driver assumes 2.
-- bus-range: PCI bus numbers covered (it is recommended for new devicetrees
-  to specify this property, to keep backwards compatibility a range of
-  0x00-0xff is assumed if not present)
