[media] v4l2: move tracepoints to video_usercopy
The (d)qbuf ioctls were traced in the low-level v4l2 ioctl function. The
trace was outside the serialization lock, so that can affect the usefulness
of the timing. In addition, the __user pointer was expected instead of a
proper kernel pointer.
By moving the tracepoints to video_usercopy we ensure that the trace calls
use the correct kernel pointer, and that it happens right after the ioctl
call to the driver, so certainly inside the serialization lock.
In addition, we only trace if the call was successful.

Both the PAL and NTSC standards are interlaced where a

In the 625 line standard ("PAL") the odd field of the frame is transmitted first,
while in the 525 standard ("NTSC") the even field is transmitted first.
This adds the possibility to change output config between the fields and standards.
This setting will reduce the "format-jitter" on the signal sent by the pixelport

There are 3 possible ways to fix it:
1) make em28xx dependent on I2C_MUX.
That sounds wrong, as the em28xx bridge doesn't have i2c muxes on it,
and just one frontend has.
Well, subdevs could eventually be converted to, instead of using dvb
i2c gate control, to use i2c mux support.
That makes sense, but it takes time and lots of effort. Not sure if
this will happen anytime soon.
2) MEDIA_SUBDRV_AUTOSELECT can be dependent of I2C and I2C_MUX.
That means that users will need to manually enable I2C_MUX on some
distributions. Not sure about others, but, on Fedora, this option is
disabled.
So, it can end by generating a number of complains from users
that their devices suddenly stopped working after a Kernel upgrade,
at least until all distros that ship Kernels with I2C_MUX enabled.
3) if MEDIA_SUBDRV_AUTOSELECT is selected, it will select I2C and I2C_MUX.
Of course, MEDIA_SUBDRV_AUTOSELECT will need to inherit all dependencies
that I2C and I2C_MUX have (only HAS_IOMEM).
The disadvantage is that, if new dependencies are added on I2C, they'll
also need to be added here.
As the hole idea of autoselect is to let the user not bother about whatever
frontend/tuner is used by a driver, IMHO, (3) is the better solution.

The omap24xx driver and the tcm825x sensor driver are the only two

Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device
API is used by out-of-tree drivers (MXC platform). This is a very bad situation
since as long as this deprecated API stays in the kernel there is no reason for
those out-of-tree drivers to convert.

staging in preparation for their removal.
If someone would be interested in getting these drivers to work, then start with
this since it's not very far from the state where they used to work:
<URL:http://vihersipuli.retiisi.org.uk/cgi-bin/gitweb.cgi?p=~sailus/linux-omap/.git;a=summary>
The branch is n800-cam. Porting to up-to-date APIs can then be done. David
might have done some work in that area, so check with him first.

[media] sn9c102: prepare for removal by moving it to staging
During the last media summit meeting it was decided to move this driver to
staging as the first step to removing it altogether.
Most webcams covered by this driver are now supported by gspca. Nobody has the
hardware to convert the remaining devices to gspca.
This driver needs a major overhaul to have it conform to the latest frameworks
and compliancy tests.
Without hardware, however, this is next to impossible. Given the fact that
this driver seems to be pretty much unused (it has been removed from Fedora
several versions ago and nobody complained about that), we decided to drop
this driver.
This patch moves it to staging. Some time in 2014 we will drop it completely.

Used synthesizer is very typical integer-N PLL, with configurable

calculate PLL N from VCO frequency. Do it that way.
Also make some cleanups for filter logic and signal strength.
