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.

AUTHORS
     The gcu driver was written by Dariusz Swiderski <dms@openbsd.org>,
     partially based on the FreeBSD driver released by Intel under the ISC
     license.
