DESCRIPTION

     The rtii driver provides support for the AIMS Lab Radiotrack II FM radio
     tuners.

     The Radiotrack II is a stereo FM tuner that can tune in the range 87.5 -
     108.0 MHz, report signal status on the current frequency, force audio
     output to mono, perform hardware signal search, and has an internal AFC.

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

     The Radiotrack II cards take only one I/O port. The I/O port is set by
     the driver to the value specified in the configuration file and must be
     either 0x20c or 0x30c.

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