-* Samsung Exynos 5440 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: "samsung,exynos5440-pcie"
-- reg: base addresses and lengths of the PCIe controller,
-- reg-names : First name should be set to "elbi".
-	And use the "config" instead of getting the configuration address space
-	from "ranges".
-	NOTE: When using the "config" property, reg-names must be set.
-- interrupts: A list of interrupt outputs for level interrupt,
-	pulse interrupt, special interrupt.
-- phys: From PHY binding. Phandle for the generic PHY.
-	Refer to Documentation/devicetree/bindings/phy/samsung-phy.txt
-
-For other common properties, refer to
-	Documentation/devicetree/bindings/pci/designware-pcie.txt
