Fix a scaling check that was failing, due to a magic number I missed fixing
during previous slice VBI changes. Now
$ v4l2-ctl -v width=480,height=480,pixelformat=MPEG
yields proper visual results again.

During the patch merge, I've added a temporary fix for v4l2_ctrl_query_fill(),
just to avoid the tree breakage. Replace those for the proper values.

Give messages originating from internal subdevs a header using the subdev's

We leaked buffers every time a device was removed, if the user had enabled
sliced VBI insertion into the MPEG stream. MythTV uses that.

The v4l2_ctrl_query_fill_std() function wasn't one the best idea I ever had.
It doesn't add anything valuable that cannot be expressed equally well with
v4l2_ctrl_query_fill and only adds overhead.
Replace it with v4l2_ctrl_query_fill() everywhere it is used and remove it
from v4l2_common.c.

Convert GPIO line functions, such a audio routing and device resets, to
v4l2_subdevices. This essentially completes the conversion of cx18 to the
v4l2_device/v4l2_subdevice framework. No regression testing has taken place as
of yet. Also an ivtv legacy bug with GPIO mux routing and going to/from radio
mode was commented, but not fixed.

This is a major perturbation to cx18 I2C device handling to convert it to the
v4l2_device/subdeivce framework. This change breaks GPIO audio multiplexer
control for the time being. It will be fixed in a coming change.

Added a new chip identifer to v4l2-chip-ident for the integrated A/V broadcast
decoder core internal to the CX23418. Completed separation and encapsulation
of the A/V decoder core interface as a v4l2_subdevice. The cx18 driver now
compiles and links again.

This is the next step in converting the cx18 driver to use the v4l2_device/
v4l2_subdevice framework. This is a straightforward conversion of the
cx18_av_*[ch] files. It compiles, but leaves the driver in an unlinkable
state at the moment.
Note, the cx18 integrated A/V digitizer will now make a host match at address 1,
as far as v4l2-dbg is concerned. That means it identifies itself as a separate
"chip", and acts as an alias to the integrated A/V decoder registers that are
also available with the host match at address 0.

Sliced VBI, in the manner that ivtv implements it as a separate data stream,
now works for 525 line 60 Hz systems like NTSC-M. It may work for 625 line
50 Hz systems, but I have more engineering work to do, to verify it is operating
properly. Sliced data insertion into the MPEG PS should be working, but is
untested.

The cx23418 appears to send Raw VBI buffers with a PTS on a per frame
basis, not per field, so process Raw VBI on a whole frame basis and reduce
some complexity. Fix VBI buffer size computation to handle a whole
frame of Raw VBI for a 625 line system, which is the worst case and will
work for 525 lines systems as well.

Fixed an endianess problem with the collection of the PTS from
the VBI buffer given to us by the encoder. Also extrapolated the
last 12 bytes of the last line of each field, to remove artifacts
created by removing the first 12 bytes of each field for raw VBI.

The Encoder will only allow the Raw VBI parameters, along with a number of
other API parameters, to take effect when no analog captures are in
progress. These parameters must be set before the first analog capture starts,
be it MPEG, VBI, YUV, etc., and cannot be changed until the last one stops. It
is not obvious to me what capture channel API parameters are shared and which
ones must be set per capture channel, so set them all for every analog
capture channel start up. This fixes the driver so that VBI capture can be
started up after the MPEG capture is going.

The old code from ivtv used a CX23415/6 PTS, which was simply left at 0 in the
cx18 driver. Since the CX23418 gives us what I think is a PTS (or some other
90 kHz clock count) with each VBI buffer, this change has the cx18 driver use
that as a PTS.

A redundant PLL divisior update for the I2S master clock after AV core
firmware load was missed in earlier PLL parameter changes. This one really
doesn't matter because it's redundant and gets overwritten, but the driver

Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.
Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.
Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

Introduce a struct v4l2_file_operations for v4l2 drivers.
Remove the unnecessary inode argument.
Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.
Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.

Use a consistent crystal value of 28.636360 MHz for computing all PLL
parameters so clocks don't have relative error due to assumed crystal
value mismatches. Also aimed to have all PLLs run their VOCs at close to
400 MHz to minimze the error of these PLLs as frequency synthesizers. Also
set the VDCLK and AIMCLK PLLs to sane values before the APU and CPU firmware
are loaded. Also fixed I2S Master clock dividers.
Many thanks to Mike Bradley and Jeff Campbell for reporting this problem and
suggesting the solution, researching and experimenting, and performing
extensive testing to support their suggested solution.
