+description: |
+  The DP83869HM device is a robust, fully-featured Gigabit (PHY) transceiver
+  with integrated PMD sublayers that supports 10BASE-Te, 100BASE-TX and
+  1000BASE-T Ethernet protocols. The DP83869 also supports 1000BASE-X and
+  100BASE-FX Fiber protocols.
+  This device interfaces to the MAC layer through Reduced GMII (RGMII) and
+  SGMII The DP83869HM supports Media Conversion in Managed mode. In this mode,
+  the DP83869HM can run 1000BASE-X-to-1000BASE-T and 100BASE-FX-to-100BASE-TX
+  conversions.  The DP83869HM can also support Bridge Conversion from RGMII to
+  SGMII and SGMII to RGMII.
+
+  Specifications about the charger can be found at:
