Mauro Carvalho Chehab
From: Hans Verkuil <hverkuil@xs4all.nl>
- Split msp3400.c into msp3400-driver.c and msp3400-kthreads.c.
- Removed experimental DFPREG ioctls. If this is really needed one
day then it should be implemented using VIDIOC_G/S_REGISTER.
- Added missing BALANCE control info for VIDIOC_QUERYCTRL.
- Still more cleanup, clarified some kernel messages.

+ *
+ * what works and what doesn't:
+ *
+ * AM-Mono
+ * Support for Hauppauge cards added (decoding handled by tuner) added by
+ * Frederic Crozat <fcrozat@mail.dotcom.fr>
+ *
+ * FM-Mono
+ * should work. The stereo modes are backward compatible to FM-mono,
+ * therefore FM-Mono should be allways available.
+ *
+ * FM-Stereo (B/G, used in germany)
+ * should work, with autodetect
+ *
+ * FM-Stereo (satellite)
+ * should work, no autodetect (i.e. default is mono, but you can
+ * switch to stereo -- untested)
+ *
+ * NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
+ * should work, with autodetect. Support for NICAM was added by
+ * Pekka Pietikainen <pp@netppl.fi>

- * programming the msp34* sound processor family
- *
- * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
- *
- * what works and what doesn't:
- *
- * AM-Mono
- * Support for Hauppauge cards added (decoding handled by tuner) added by
- * Frederic Crozat <fcrozat@mail.dotcom.fr>
- *
- * FM-Mono
- * should work. The stereo modes are backward compatible to FM-mono,
- * therefore FM-Mono should be allways available.
- *
- * FM-Stereo (B/G, used in germany)
- * should work, with autodetect
- *
- * FM-Stereo (satellite)
- * should work, no autodetect (i.e. default is mono, but you can
- * switch to stereo -- untested)
- *
- * NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
- * should work, with autodetect. Support for NICAM was added by
- * Pekka Pietikainen <pp@netppl.fi>
- *
