V4L2 API (chapter 1.5) states that:
Drivers must implement all input ioctls when the device has one
or more inputs, all output ioctls when the device has one or more outputs.
When the device has any audio inputs or outputs the driver must set the
V4L2_CAP_AUDIO flag in the struct v4l2_capability returned by the
VIDIOC_QUERYCAP ioctl.
So, devices without audio input should return -EINVAL.

In the past, some devices with saa711x had their parameters controlled
directly inside em28xx driver, instead of using their proper module for
it.
Due to that, the ac97 controls were mixed with saa711x ones.
Older patches removed all saa711x controls, but we still need to control
ac97 devices on em28xx, since we don't have a separate v4l2 device for
it.
The proper way to address is to create a separate ac97 v4l2 device.
While we don't have it, we should clean up the code to allow having a
better view of what is part of em28xx core code and what's due to ac97
control inside it.

Register 0x13 seems to be a sort of image control, maybe gamma, white
level or black level. Lower values produce better images, while higher
values increases the contrast and shifts colors to green. 0xff produces
a black image. This register is not Silvercrest-specific, so its code
should be moved to a better place.
If this register is left alone, a random value can be found at the
register, producing weird results.
While here, let's remove register 0x0d, as it had no noticed effect at
the image.

Silvercrest mt9v011 sensor produces a 640x480 image. However,
previously, the code were getting only half of the lines and merging two
consecutive frames to "produce" a 640x480 image.
With the addition of progressive mode, now em28xx is working with a full
image. However, when the number of lines is bigger than 240, the
beginning of some odd lines are filled with blank.
After lots of testing, and physically checking the device for a Xtal, it
was noticed experimentally that mt9v011 is using em28xx XCLK as its
clock. Due to that, changing XCLK value changes the maximum speed of the
stream.
At the tests, it were possible to produce up to 32 fps, using a 30 MHz
XCLK. However, at that rate, the artifacts happen even at 320x240. Lower
values of XCLK produces artifacts only at 640x480.
At some values of xclk (for example XCLKK = 6 MHz, 640x480), it is
possible to see an invalid sucession of artifacts with this pattern:
.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
(where the dots represent the blanked pixels)
So, it seems that a waveform in the format of a ramp is interferring at
the image.
The cause of this interference is currently unknown. Some possibilities
are:
- electrical interference (maybe this device is broken?);
- some issue at mt9v011 programming;
- some bug at em28xx chip.
So, for now, let's be conservative and use a value of XCLK that we know
for sure that it won't cause artifacts.
As I'm waiting for more of such devices with different em28xx chipset
revisions, I'll have the opportunity to double check the issue with
other pieces of hardware.
Later patches can vary XCLK depending on the vertical resolutions, if a
proper fix is not discovered.

Due to historical reasons, em28xx driver gets two consecutive frames and
fold them into an unique framing, doing interlacing. While this works
fine for TV images, this produces two bad effects with webcams:
1) webcam images are progressive. Merging two consecutive images produce
interlacing artifacts on the image;
2) since the driver needs to get two frames, it reduces the maximum
frame rate by two.

While trying to fix an mt9v001 webcam, I noticed that HSCALE/VSCALE do
work with em28xx + webcam. The issue is that the scaling setup depends
on the number of visible rows/cols of the input image.
With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling
is different from a normal TV image (720x480 on NTSC). This were causing
a wrong scaling and a previous patch disabled scaling.
As each sensor have their different resolution setting, the xres/yres
should be adjusted accordingly with the input sensor.

Let card drivers probe for IR receiver devices and instantiate them if

completely, but I suspect this won't be possible for all card types.
There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.
Also, the special cases in saa7134-i2c should probably be handled on a

probing extra addresses on all boards. I'll give it a try later.

Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any
data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion.
It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and
reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.
