<p class="Pp">The <code class="Nm">rtii</code> driver provides support for the
    AIMS Lab Radiotrack II FM radio tuners.</p>
<p class="Pp">The Radiotrack II is a stereo FM tuner that allows to 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.</p>
<p class="Pp">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.</p>
<p class="Pp">Philips Semiconductors released two almost identical chips TEA5757
    and TEA5759. The TEA5757 is used in FM-standards in which the local
    oscillator frequency is above the radio frequency (e.g. European and
    American standards). The TEA5759 is the version in which the oscillator
    frequency is below the radio frequency (e.g. Japanese standards). The option
    <var class="Va">RADIO_TEA5759</var> changes the algorithm of frequency
    calculation for the TEA5757 based cards to conform with the Japanese
    standards.</p>
