The fix for the UV swapping in qcif mode with the ov6630, which I did
to fix this issue on a ov518 cam with an ov66308AF, causes UV swapping in
qcif with another cam of mine with the ov518 and an ov66308AE, so this
patch changes the code to differentiate between the ov66308AF and other
ov6630 versions, and restricts the UV swap fix to the ov66308AF.

This patch adds autobrightness (so that it can
be turned off to make the already present brightness
control work) and light frequency filtering controls.

The lightfreq control needed 2 different entries
in the ctrls array, as the number of options differs
depending on the sensor. Always one of the 2 entires is
disabled ofcourse.

Since videobuf-dma-contig is designed to handle physically contiguous
memory, this patch modifies the videobuf-dma-contig code to only accept a
user space pointer to physically contiguous memory.  For now only
VM_PFNMAP vmas are supported, so forget hotplug.

On SuperH Mobile we use this with our sh_mobile_ceu_camera driver together
with various multimedia accelerator blocks that are exported to user space
using UIO.  The UIO kernel code exports physically contiguous memory to
user space and lets the user space application mmap() this memory and pass
a pointer using the USERPTR interface for V4L2 zero copy operation.

With this approach we support zero copy capture, hardware scaling and
various forms of hardware encoding and decoding.

This patch changes cx88_set_stereo to avoid resetting all of the audio
registers on stereo/mono change if the audio standard is A2, and set
only the AUD_CTL register. The benefit of this method is that it
eliminates the annoying clicking noise on setting the audio mode to
stereo or mono.

The driver had used the same method 1.5 years ago (and for FM radio it
still does), but a pretty big cleanup commit changed it to the
"complete audio reset" method, although the reason for this move was
not clear. (If somebody knows why it was necessary, please let me
know!)

The sole purpose of the audio thread is to detect if stereo transmission is
available, and if it is, then switch to stereo mode (and switch back, if it's
no longer available). This manual autodetection is useful for some audio
standards (e.g. A2) where cx88_get_stereo CAN detect stereo sound, but the
cx2388x chip CANNOT auto-detect stereo sound.

However, for other audio standards, the cx2388x chip CAN auto-detect the stereo
sound, so the manual autodetection in the audio thread is not needed. In fact,
it can cause serious problems because for some of these audio standards,
cx88_get_stereo CANNOT detect the presence of stereo sound.  Besides that, if
the hardware automatically detects stereo/mono sound, you cannot set
core->audiomode_current to the real current audio mode on channel change.

With this patch, the manual autodetection is only used if audiomode_current is
known after a channel change (because of the initial mono mode), and
hardware-based stereo autodetecion is not applicable for the current audio
standard.

The patch implements reliable stereo and sap detection for the A2 sound
standard.  This is achieved by processing the samples of the audio RDS fifo of
the cx2388x chip. A2M, EIAJ and BTSC stereo/sap detection is also possible with
this new approach, but it's not implemented yet. Stereo detection when alsa
handles the sound also does not work yet.

Since i2c autoprobing is no longer supported by v4l2 we need to make sure
that the i2c modules are linked before the v4l2 modules. The v4l2 modules
now rely on the presence of the i2c modules, so these must have initialized
themselves before the v4l2 modules.

The exception is the ir-kbd-i2c module, which is the only one still using
autoprobing. This one should be loaded at the end of the v4l2 module. Loading
it earlier actually causes problems with tveeprom. Once ir-kbd-i2c is no
longer autoprobing, then it has to move up as well.

This is only an issue when everything is compiled into the kernel.

Fix a regression caused by changeset 9133:64aed7485a43 - v4l: disconnect
kernel number from minor

Before the above changeset, ov511_probe used to allow forcing to use a
certain specific set of video devices, like:

modprobe ov511 unit_video=4,1,3 num_uv=3

So, assuming that you have 5 ov511 devices, and connect they one by one,
they'll gain the following device numbers (at the connection order):
/dev/video4
/dev/video1
/dev/video3
/dev/video0
/dev/video2

However, this was changed due to this change at video_register_device():

+ nr = find_next_zero_bit(video_nums[type], minor_cnt, nr == -1 ? 0 : nr);

With the previous behavior, a trial to register on an already allocated mirror
would fail, and a loop would get the next requested minor. However, the current
behavior is to get the next available minor instead of failing. Due to that,
this means that the above modprobe parameter will give, instead:

/dev/video5
/dev/video6
/dev/video7
/dev/video8
/dev/video9

In order to restore the original behavior, a static var were added,
storing the amount of already registered devices.

While there, it also fixes the locking of the probe/disconnect functions.

A bunch of V4L drivers generate BTN_0 instead of KEY_CAMERA key presses.

X11 is able to handle KEY_CAMERA automatically these days while BTN_0 is
not treated at all.  Thus it would be of big benefit if the camera drivers
would consistently generate KEY_CAMERA.  Some drivers (uvc) already do,
this patch updates the remaining drivers to do the same.

I only possess a limited set of webcams, so this isn't tested with all
cameras.  The patch is rather trivial and compile tested, so I'd say it's
still good enough to get merged.
