+The
+.Nm
+driver provides access to the miibus that is hidden behind the GCU device. It
+is used to control PHY's on embedded designs utilizing Intel's EP80579
+chips.
+.Pp
+The GCU also provides access to CAN, SSP and TDM signal strength drivers,
+but since they are not supported by OpenBSD the driver does not provide any
+functionality related to them.
