+title: Freescale i.MX6 PCIe host controller
+
+maintainers:
+ - Lucas Stach <l.stach@pengutronix.de>
+ - Richard Zhu <hongxing.zhu@nxp.com>
+
+description: |+
+ This PCIe host controller is based on the Synopsys DesignWare PCIe IP
+ and thus inherits all the common properties defined in snps,dw-pcie.yaml.
+ The controller instances are dual mode where in they can work either in
+ Root Port mode or Endpoint mode but one at a time.
+
+ See fsl,imx6q-pcie-ep.yaml for details on the Endpoint mode device tree
+ bindings.
