    Subject[PATCH v5] [resend] radio-sf16fmr2: convert to generic TEA575x interface
    From
    Date
    Convert radio-sf16fmr2 to use generic TEA575x implementation. Most of the
    driver code goes away as SF16-FMR2 is basically just a TEA5757 tuner
    connected to ISA bus.
    The card can optionally be equipped with PT2254A volume control (equivalent
    of TC9154AP) - the volume setting is completely reworked (with balance control
    added) and tested.

    - * Notes on the hardware
    - *
    - * Frequency control is done digitally -- ie out(port,encodefreq(95.8));
    - * No volume control - only mute/unmute - you have to use line volume
    - *
    - * For read stereo/mono you must wait 0.1 sec after set frequency and
    - * card unmuted so I set frequency on unmute
    - * Signal handling seem to work only on autoscanning (not implemented)
