gcu
driver provides access to the miibus that is
hidden behind the GCU device. It is used to control PHYs on embedded designs
utilizing Intel's EP80579 chips.
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.
