 * Synopsys Designware PCIe interface
 
 Required properties:
-- compatible: should contain "snps,dw-pcie" to identify the
-        core, plus an identifier for the specific instance, such
-        as "samsung,exynos5440-pcie" or "fsl,imx6q-pcie".
-- reg: base addresses and lengths of the pcie controller,
-        the phy controller, additional register for the phy controller.
-- interrupts: interrupt values for level interrupt,
-        pulse interrupt, special interrupt.
-- clocks: from common clock binding: handle to pci clock.
-- clock-names: from common clock binding: should be "pcie" and "pcie_bus".
+- compatible: should contain "snps,dw-pcie" to identify the core.
 - #address-cells: set to <3>
 - #size-cells: set to <2>
 - device_type: set to "pci"
