   5  * Devicetree for the Inteno XG6846 router, mostly used as a
   6  * media converter from fiber to twisted pair ethernet
   7  * "fiber modem" in many households in Sweden. The Marvell
   8  * switch has one of its ports connected to an SFP (Small Form
   9  * Factor pluggable) optical fiber receiver, which is bridged
  10  * to the twisted pair connector LAN1.
  11  *
  12  * This device tree is inspired by research from the OpenWrt
  13  * and Sweclockers forums, including contributions from
  14  * NPeca75, mrhaav and csom.

  16  * Some devices have a USB type A host receptacle mounted,
  17  * some do not.
