      [media] go7007: add motion detection support · 0ee58f84
      由 Hans Verkuil 提交于 
      This patch adds motion detection support to the go7007 driver using the new
motion detection controls, events.

The global motion detection works fine, but the regional motion detection
support probably needs more work. There seems to be some interaction between
regions that makes setting correct thresholds difficult. The exact meaning of
the thresholds isn't entirely clear either.

I do not have any documentation, the only information I have is the custom code
in the driver and a modet.c application.

      This patch were applied by mistake, as it were rejected by Don, who
requested it to be broken into per-change patches.

This reverts commit 0982db20.

      [media] staging: media: go7007: Adlink MPG24 board issues · 0982db20
      由 Volokh Konstantin 提交于 
      This issuses applyed only for Adlink MPG24 board with go7007
 & wis2804, all whese changes was tested for continuos
 load&restart mode

This is minimal changes needed for start up go7007&wis2804 to work correctly
  in 3.4 branch

Changes:
  - When go7007 reset device, i2c was not worked (need rewrite GPIO5)
  - As wis2804 has i2c_addr=0x00/*really*/, so Need set I2C_CLIENT_TEN flag for validity
  - some main nonzero initialization, rewrites with kzalloc instead kmalloc
  - STATUS_SHUTDOWN was placed in incorrect place, so if firmware wasn`t loaded, we
    failed v4l2_device_unregister with kernel panic (OOPS)
  - some new v4l2 style features as call_all(...s_stream...) for using subdev calls
  - wis-tw2804.ko module code was incompatible with 3.4 branch in initialization v4l2_subdev parts.
    now i2c_get_clientdata(...) contains v4l2_subdev struct instead non standart wis_tw2804 struct

Adds:
  - Additional chipset tw2804 controls with: gain,auto gain,inputs[0,1],color kill,chroma gain,gain balances,
    for all 4 channels (from tw2804.pdf)
  - Power control for each 4 ADC (tw2804) up when s_stream(...,1), down otherwise

      [media] go7007: MJPEG buffer overflow · a716e9d7
      由 Pete Eberlein 提交于 
      The go7007 driver has a potential buffer overflow and pointer corruption
bug which causes a crash while capturing MJPEG. The motion detection
(MODET) active_map array can be overflowed by JPEG frame data that
emulates a MODET start code. The active_map overflow overwrites the
active_buf pointer, causing a crash.

The JPEG data that emulated MODET start code was being removed from the
output, resulting in garbled JPEG frames. Therefore ignore MODET start
codes when MODET is not enabled.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      由 Tejun Heo 提交于 
      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.

      go7007: Convert to the new i2c device binding model · 7400516a
      由 Jean Delvare 提交于 
      Move the go7007 driver away from the legacy i2c binding model, which
is going away really soon now.

The I2C addresses of the audio and video chips in s2250-board didn't
look quite right, apparently they were left-aligned values when Linux
wants right-aligned values, so I fixed them too.
