+.Sh NAME
+.Nm gtp
+.Nd Gemtek PCI FM radio device driver
+.Sh SYNOPSIS
+.Cd "gtp* at pci? flags 0x00"
+.Cd "radio* at gtp?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the Gemtek PCI and Guillemot MaxiRadio FM2000
+FM radio tuners.
+.Pp
+The Gemtek PCI cards are stereo FM tuners that allow to tune in the range
+87.5 - 108.0 MHz, report signal status and stereo/mono on the current
+frequency, force audio output to mono, perform hardware signal search,
+and have an internal AFC.
+.Pp
+The card is based on the TEA5757 chip, see
+.Xr radio 4
+for details.
+.Pp
+The flags control the driver behavior. For example, with flags 0x01 the driver
+will assume that a TEA5759 chip is used.
+.Sh BUGS
+It is impossible to determine which frequency the card is tuned to.
+Thus, the driver will report an internally stored value even if it is not
+correct (changed by some program that uses direct port access).
+.Sh SEE ALSO
+.Xr pci 4 ,
+.Xr radio 4 ,
+.Xr radio 9
+.Sh AUTHORS
+The
+.Nm
+driver and the man page was written by
+.An Vladimir Popov Aq jumbo@narod.ru .
+.Sh HISTORY
+The
+.Nm
+device driver appeared in
+.Ox 3.2 .
