VIDIOC_DBG_G_CHIP_IDENT is a prerequisite for the G/S_REGISTER ioctls.
In addition, add support to call G/S_REGISTER for supporting i2c devices.

Hmm... G/S_AUDIO is also used to query/set the capabilities and the mode
of an input, which IMHO makes sense even if the input is the only one
the device has ?
Don't you think that it's also somehow inconsistent, because for the
video inputs (G/S_INPUT) the spec says:
"This ioctl will fail only when there are no video inputs, returning
EINVAL." ?

Frank

You are right, but there are problems with the implementation in this driver.
First of all, there is no ENUMAUDIO ioctl implemented, so applications were
never able to enumerate the audio inputs.
Now, it is possible to add this (and I have done this in this tree:
http://git.linuxtv.org/hverkuil/media_tree.git/shortlog/refs/heads/bttv2).
However, the card definitions are unreliable with respect to the number of
audio inputs. So you may end up with a driver reporting incorrect information.
I tried it in the bttv2 branch and frankly it became rather messy.
Given the fact that there was never an ENUMAUDIO ioctl in the first place
I decided that it was better not to have these ioctls at all. Also, the
V4L2_CAP_AUDIO was never set, and they are incorrect anyway for boards that
do not have an audio input at all (common for surveillance boards).
There are other drivers as well that do not implement this, so applications
cannot rely on this ioctl being present.
I will update the commit message before I do the pull request, though. It
should be extended with the information above.
Regards,
Hans

I checked your bttv2 branch and it's looking not that bad !
If I'm understanding correctly, your main concern is, that the board
information isn't reliable/correct ?
Hmm... it seems that (although commented out) nearly all boards have the
.audio_inputs field set, which leaves rooms for hope...
OTOH, even if the board info about the audio inputs is wrong, this
wouldn't have any consequences for the video input, right ?
The additional audio inputs just won't work. And that's something we can
fix step by step (if anybody cares ;) ).
So there is no risk of regressions and a good chance to get a missing
functionality work.
In that case I would vote for adding ENUM/G/S_AUDIO.

Sure, they _shouldn't_.

That's probably the best solution for 3.9.

From: Hans Verkuil <hans.verkuil@cisco.com>
If no tuner is present, then disable the tuner and frequency ioctls.
We can remove a number of checks from those ioctls testing for the presence
of a tuner.
Also remove some tuner type checks (now done by the core) and fix an
error return when the prio check fails.
Finally some 'unlikely' statements are removed since those only make sense
in tightly often executed loops, otherwise they just clutter up the code.

Set an initial frequencies when the driver is loaded. That way G_FREQUENCY will
give a frequency that corresponds with reality.

- don't return -EINVAL for invalid field types, handle those as if it
was FIELD_ANY.
- the handling of FIELD_SEQ_BT/TB was wrong as well: if such field formats
aren't supported, then fall back to FIELD_ANY instead of returning an error.

To: linux-media; +Cc: Hans Verkuil
From: Hans Verkuil <hans.verkuil@cisco.com>
Note that the private chroma agc control has been replaced with the standard
CHROMA_AGC control.
Also fixes a mute/automute problem where closing the file handle would force
mute on. That's not what you want since that would make the mute state out of
sync with the mute control. Instead check against the user count.

Probe for additional tvaudio devices, and allow tvaudio+tda7432 to
co-exist. My STB TV PCI FM bttv card has a tda7432, a tda9850 and a
tea6420 and with this patch it finally works again (probably for the
first time in many years).

try_fmt_vid_overlay should map incorrect sizes and fields to valid values.
It also expects that an initial overlay size is defined so g_fmt_vid_overlay

Just opening the radio tuner should not cause a switch to the radio tuner.
Only after calling g/s_tuner or g/s_frequency should this happen.
This prevents audio being unmuted as soon as the driver is loaded because
some process opens /dev/radioX just to see what sort of node it is, which
switches on the radio tuner and unmutes audio.
This code can be improved further by actually keeping track of who owns the
tuner and returning -EBUSY if switching tuner modes will cause problems.
But for now just fix the annoying case where on boot the radio turns on
automatically.
