|

* 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.
