+description: |
+  The DP83822 is a low-power, single-port, 10/100 Mbps Ethernet PHY. It
+  provides all of the physical layer functions needed to transmit and receive
+  data over standard, twisted-pair cables or to connect to an external,
+  fiber-optic transceiver. Additionally, the DP83822 provides flexibility to
+  connect to a MAC through a standard MII, RMII, or RGMII interface
+
+  Specifications about the charger can be found at:
+    http://www.ti.com/lit/ds/symlink/dp83822i.pdf
