V4L/DVB (3700): Remove obsolete commands from tvp5150.c
[linux-2.6] / drivers / media / video / msp3400-driver.c
1 /*
2  * Programming the mspx4xx sound processor family
3  *
4  * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
5  *
6  * what works and what doesn't:
7  *
8  *  AM-Mono
9  *      Support for Hauppauge cards added (decoding handled by tuner) added by
10  *      Frederic Crozat <fcrozat@mail.dotcom.fr>
11  *
12  *  FM-Mono
13  *      should work. The stereo modes are backward compatible to FM-mono,
14  *      therefore FM-Mono should be allways available.
15  *
16  *  FM-Stereo (B/G, used in germany)
17  *      should work, with autodetect
18  *
19  *  FM-Stereo (satellite)
20  *      should work, no autodetect (i.e. default is mono, but you can
21  *      switch to stereo -- untested)
22  *
23  *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
24  *      should work, with autodetect. Support for NICAM was added by
25  *      Pekka Pietikainen <pp@netppl.fi>
26  *
27  * TODO:
28  *   - better SAT support
29  *
30  * 980623  Thomas Sailer (sailer@ife.ee.ethz.ch)
