     gtp - Gemtek PCI FM radio device driver

SYNOPSIS    [Toc]    [Back]

     gtp*   at pci? dev ? function ? flags 0x00
     radio* at gtp?

DESCRIPTION    [Toc]    [Back]

     The gtp driver provides  support  for  the  Gemtek  PCI  and
Guillemot MaxiRadio
 FM2000 FM radio tuners.

     The  Gemtek  PCI cards are stereo FM tuners that can 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.

     The card is based on the TEA5757 chip; see radio(4) for  details.

     The  flags  control  the driver behavior.  For example, with
flags 0x01 the
     driver will assume that a TEA5759 chip is used.

BUGS    [Toc]    [Back]

     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).
