+title: Socionext UniPhier PCIe host controller
+
+description: |
+ UniPhier PCIe host controller is based on the Synopsys DesignWare
+ PCI core. It shares common features with the PCIe DesignWare core and
+ inherits common properties defined in
+ Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml.
