+ * Devicetree for the Inteno XG6846 router, mostly used as a
+ * media converter from fiber to twisted pair ethernet
+ * "fiber modem" in many households in Sweden. The Marvell
+ * switch has one of its ports connected to an SFP (Small Form
+ * Factor pluggable) optical fiber receiver, which is bridged
+ * to the twisted pair connector LAN1.
+ *
+ * This device tree is inspired by research from the OpenWrt
+ * and Sweclockers forums, including contributions from
+ * NPeca75, mrhaav and csom.
+ *
+ * Some devices have a USB type A host receptacle mounted,
+ * some do not.
