5fee334039 V4L/DVB: em28xx: rework buffer pointer tracking for offset to start of video
Rework the logic for tracking the amount of data copied to the VBI buffer, to
address problem found where the video lines are several bytes shifted to the
right (and the leading pixels in the first line rendered are garbage).  This
would occur because the copy function would advance the pointer when detecting
headers, but the caller would not adjust the length actually copied.

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

622b828ab7 V4L/DVB (13238): v4l2_subdev: rename tuner s_standby operation to core s_power
Upcoming I2C v4l2_subdev drivers need a way to control the subdevice
power state from the core. This use case is already partially covered by
the tuner s_standby operation, but no way to explicitly come back from
the standby state is available.

Rename the tuner s_standby operation to core s_power, and fix tuner
drivers accordingly. The tuner core will call s_power(0) instead of
s_standby(). No explicit call to s_power(1) is required for tuners as
they are supposed to wake up from standby automatically.

da52a55cff V4L/DVB (12741): em28xx: make video isoc stream work when VBI is enabled
Add code enabling the VBI registers for variants of the em28xx chip that
support VBI, and make sure the isoc streaming code continues to work for
the video component of the stream (note the video and vbi data arrive
intermixed on the same isoc pipe).

Note that this version just drops the actual VBI data onto the floor as
opposed to processing it.  The "#ifdef 0" tags are for the videobuf code that
appears in the next patch in this series.

We created a separate version of the isoc_copy version for parsing the version
of the stream that includes VBI data.  In theory, they might be able to be
merged at some point in the future, but the initial goal is to ensure that we
do not cause any regressions with devices that do not have VBI support.

a98f6af96e V4L/DVB (12274): em28xx-video: better implement ac97 control ioctls
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.

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.

module (tda9874a). This patch improves em28xx infrastructure to support
an external audio processor and fixes the Compro VideoMate entry to work
with it.

em28xx were trying to access the third input entry, even for boards that
don't support it.

This patch reviews the input mux selection fixing this bug and a few
other troubles, like not validating the input on one userspace ioctl.

aecde8b53b V4L/DVB (10141): v4l2: debugging API changed to match against driver name instead of ID.
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.

bec43661b1 V4L/DVB (10135): v4l2: introduce v4l2_file_operations.
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.

2e5ef2dfc4 V4L/DVB (9980): em28xx: simplify analog logic
Now, just two routines are enough for analog: the first one configs the analog
part and register V4L2 devices, and the second one release analog devices.

After this patch, it will be easier to transform em28xx-video into an em28xx
extension, loaded only on analog devices.

1a23f81b7d V4L/DVB (9979): em28xx: move usb probe code to a proper place
em28xx-video were holding several code that are not specific to V4L2
interface.

This patch moves the core code for em28xx-core, and usb probing code
into em28xx-cards.

This opens the possibility of breaking em28xx into a core module and a
V4L2 module, loaded only on devices that have analog interfaces.

Some cleanup may be done at em28xx-cards to optimize the config code.
