b331def2d3 V4L/DVB (4982): Fix broken audio mode handling for line-in in msp3400.
The wrong matrix was used when an external input was selected instead of
the tuner input. The rxsubchans field was also not initialized to STEREO
for an external input. And finally the msp34xxg_detect_stereo() should
not try to detect stereo for an external input, that code is for the
tuner input only.
Together these bugs made it hit 'n miss whether you ever got stereo out
of the msp3400 for an external input.

de98cdaf7e V4L/DVB (4688): Fix msp343xG handling (regression from 2.6.16)
The msp3430G and msp3435G models cannot do Automatic Standard Detection.
So these should be forced to BTSC. These chips are early production versions
for the msp34xxG series and are quite rare.
The workaround for kernel 2.6.18 is to use 'standard=32' as msp3400
module option. Due to broken handling of the 'standard' option in 2.6.17 there is
no workaround possible for that kernel.

07151724a3 V4L/DVB (3702): Make msp3400 routing defines more consistent
Renamed various msp3400 routing defines to be more consistent and less
confusing. Esp. the MSP_DSP_OUT defines were confusing since it is really
a DSP input.

0020d3ef91 V4L/DVB (3693): Fix msp3400c and bttv stereo/mono/bilingual detection/handling
- msp3400c did not detect the second carrier, thus being always mono.
- properly mute the msp3400c while detecting the carrier.
- fix checks on the presence of scart2/3 inputs and scart 2 output.
- implement proper audio mode fallbacks for msp3400c/d, identical to the
  way msp3400g works.
- MODE_STEREO no longer produces dual languages when set for a bilingual
  transmission, instead it falls back to LANG1. Use LANG1_LANG2 to hear
  both languages of a bilingual transmission. This is much more intuitive
  for the user and is in accordance with the preferred usage in the v4l2
  specification.
- bttv tried to implement v4l2 calls with v4l1 calls to the i2c devices,
  completely mangling the audmode/rxsubchans handling. v4l2 calls now do
  v4l2 calls to the i2c devices.
- fixed broken i2c_vidiocschan in bttv.
- add start/end lines to LOG_STATUS.

cc33668b1e V4L/DVB (3667a): Fix SAP + stereo mode at msp3400
It should be V4L2_TUNER_MODE_LANG1_LANG2. What the code does is check if 
we are NTSC and a SAP channel is available. If so, then the msp3400 
should switch to standard 0x21 if the user wants to hear the SAP 
channel, which is for audio modes LANG2 (aka SAP) and LANG1_LANG2 
(bilingual).

In the msp3400 driver STEREO is abused for bilingual in PAL. Bilingual 
never worked with NTSC in the past and I decided that I'd better not 
use the bad PAL example.

7061561e64 V4L/DVB (3663): Fix msp3400c wait time and better audio mode fallbacks
- The wait time until the first time the audio mode was detected was
  1+5=6 seconds instead of just 1 second (wrong statement order).
  msp3400c specific bug.
- Implemented audio mode fallback for msp3400c/d just like the msp3400g
  does automatically. E.g. fallback to stereo if no second language exists,
  etc.

301e22d691 V4L/DVB (3584): Implement V4L2_TUNER_MODE_LANG1_LANG2 audio mode
Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER).
This mode allows the user to select both languages of a bilingual transmission,
one language on the left, one on the right audio channel. If there is no
bilingual transmission, or it is not supported, then this mode should act like
V4L2_TUNER_MODE_STEREO.
This mode is introduced for PVR-like drivers where it is useful to be able to
record both languages of a bilingual broadcast.

8bf2f8e747 V4L/DVB (3577): Cleanup audio input handling
Cleanup audio input handling in bttv and tvaudio:
- inputs were specified that were never used
- mute was handled as a special input which led to confusing code
- confusing naming made it difficult to see if the setting was for
  i2c or gpio.
The old audiochip.h input names moved to tvaudio.h. Currently this
is used both by tvaudio and msp3400 until the msp3400 implements the
new msp3400-specific inputs.
Detect in bttv the tvaudio and msp3400 i2c clients and use these
client pointers to set the inputs directly instead of broadcasting the
command.
Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be
replaced again later by the new ROUTING commands.
Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is
a user level command and not to be used internally. It wasn't called at
all anyway.

d312a46e53 V4L/DVB (3324): msp3400 audio handling bug fixes.
- Check capabilities for audio settings (volume, balance,
bass, treble, loudness, mute)
- added loudness support
- added missing VIDEO_AUDIO_BALANCE flags for v4l1 compatibility
- do not call msp_any_detect_stereo for non-autoselect chips to
retrieve the current stereo setting: that will temporarily mute
the sound. It is only needed when the stereo mode might be
changed, and for autoselect msp processors that do not periodically
need to update their stereo setting.
- do not wake up the thread if the standard did not change. Prevents
temporary audio drop-out if the standard is set to the same value.
- fix confused stereo detect code where V4L2_TUNER_SUB_STEREO and
V4L2_TUNER_MODE_STEREO values were used incorrectly.
- stereo mode reporting was broken (v4l2 value used to index a
string array expecting v4l1 mode values).
- do not set dsp register 0x30 in the 3410d thread: that register
does not exist for pre-'G' revision msp chips.
