NAME

     gcu - Intel EP80579 Global Configuration Unit


SYNOPSIS

     gcu* at pci?


DESCRIPTION

     The 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.
