The correct LLC DLL phase depends on the board layout, so this

Also updated the platform_data in ezkit to ensure that what was the old

[media] adv7842: 625/525 line standard jitter fix
Both the PAL and NTSC standards are interlaced where a
frame consist of two fields. Total number of lines in a frame in both systems
are an odd number so the two fields will have different length.
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
moving the difference between the fields to vertical front/back-porch only.

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.

[media] omap24xx/tcm825x: move to staging for future removal
The omap24xx driver and the tcm825x sensor driver are the only two
remaining drivers to still use the old deprecated v4l2-int-device API.
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.
This patch moves v4l2-int-device and the two drivers that depend on it to
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:

[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.

Optimal AGC is highly depended on used RF tuner and due to that
it is already included to chip configuration. However, inittab
has default AGC value, which was later replaced by one from config.
Add also comment to all chip configuration options about default
values and if those are needed to set or not.

Used synthesizer is very typical integer-N PLL, with configurable
reference frequency divider, output frequency divider and of
course N itself. Most common method to calculate values is first
select output divider, then calculate VCO frequency and finally
calculate PLL N from VCO frequency. Do it that way.
Also make some cleanups for filter logic and signal strength.

[media] dib8000: make a better estimation for dBm
Use multiple linear segments to better interpolate the dBm
for the signal strength.
The table that converts from linear strength to dB was
empirically determinated with the help of a signal generator
(DTA-2111).
The entries from -35dBm to -22.5dBm were taken using just
the signal generator and the board.
For the entries from -36dBm to -51dBm, a 16 dB tap was used,
in order to extend its range.
Signals below to -51dBm are just linearly interpolated.
