da673e603b [media] mt9m111: properly implement .s_crop and .s_fmt(), reset on STREAMON
mt9m111 camera sensors support cropping and scaling. The current
implementation is broken. For example, .s_crop() sets output frame sizes
instead of the input cropping window. This patch adds a proper implementation
of these methods. Besides it adds a sensor-disable and -enable operations
on first open() and last close() respectively, to save power while closed and
to return the camera to the default power-on state.

8843d119ea [media] soc-camera: remove redundant parameter from .set_bus_param()
The "pixfmt" parameter of the struct soc_camera_host_ops::set_bus_param()
method is redundant, because at the time, when this method is called,
pixfmt is guaranteed to be equal to icd->current_fmt->host_fmt->fourcc.
Remove this parameter and update all drivers accordingly.

31e582e926 [media] pwc: Properly fill all fields on try_fmt
Before this patch the resulting values from a try_fmt were different then
those from a s_fmt with the same parameters. try_fmt simply did not
touch / fill some values like bytesperline at all.

This patch also corrects bytesperline to the proper value for a planar
format such as the YUV420P format the pwc driver produces, which is
the bytesperline value for the biggest plane, rather then those
of all planes added together.

c20d78cde3 [media] pwc: Rework locking
While testing gtk-v4l's new ctrl event code, I hit the following deadlock
in the pwc driver:

Thread 1:
-Does a VIDIOC_G_CTRL
-video2_ioctl takes the modlock
-video2_ioctl calls v4l2_g_ctrl
-v4l2_g_ctrl takes the ctrl_handler lock
-v4l2_g_ctrl calls pwc_g_volatile_ctrl
-pwc_g_volatile_ctrl releases the modlock as the usb transfer can take a
 significant amount of time and we don't want to block DQBUF / QBUF too long
Thread 2:
-Does a VIDIOC_FOO_CTRL
-video2_ioctl takes the modlock
-video2_ioctl calls v4l2_foo_ctrl
-v4l2_foo_ctrl blocks while trying to take the ctrl_handler lock
Thread 1:
-Blocks while trying to re-take the modlock, as its caller will eventually
 unlock that

Now we have thread 1 waiting for the modlock while holding the ctrl_handler
lock and thread 2 waiting for the ctrl_handler lock while holding the
modlock -> deadlock.

Conclusion:
1) We cannot unlock modlock from pwc_s_ctrl / pwc_g_volatile_ctrl,
   but this can cause QBUF / DQBUF to block for up to a full second
2) After evaluating various option I came to the conclusion that pwc should
   stop using the v4l2 core locking, and instead do its own locking

Thus this patch stops pwc using the v4l2 core locking, and replaces that with
it doing its own locking where necessary.

d80dd5d036 [media] gscpa - sn9c20x: Add sd_isoc_init ensuring enough bw when i420 fmt
When using the SN9C20X_I420 fmt the sn9c20x needs more bandwidth
than our regular bandwidth calculations reserve.

This patch adds a sd_isoc_init function, which forces the use of a specific
altsetting when using the SN9C20X_I420 fmt.

This fixes the bottom 10-30% of the image getting corrupted when using
the SN9C20X_I420 fmt (which is the default fmt).

eb3fb7c963 [media] gspca: Add a need_max_bandwidth flag to sd_desc
Some cameras will pretty much entirely fill all the image buffers all the
time even though they are using compression.

This patch adds a flag to sd_desc, which drivers for such cameras can set.

When this flag is set the bandwidth calculation code will no longer
assume that the image buffer size is a worst case and less bandwidth than
imagebufsize * fps will be used on average.

This patch sets this new flag for 3 drivers:
* For spca561 (for rev12a cameras) and nw80x cams as these simply don't work
  when given less bandwidth than imagebufsize * fps.
* For sn9c20x cameras, because these show severy jpeg artifacts when
  given less bandwidth than imagebufsize * fps and since these are usb2
  cameras there is plenty bandwidth anyways.

74900b4715 [media] cx25840: Hauppauge HVR1850 Analog driver support
Adding support for the CX23888 DIF.
Changes regression tested against the HVR1700 and HVR1800.

Split out much of the set and init handling of the cx23885 based
cards into their own functions. Added the DIF initialization code
for each supported IF.

Updated the cx23885 code to correctly initialize cx23888 based
video/audio decoders.

Enabled Closed Caption support for CX23885 based cards during
initialization.

9def5ed716 [media] cx23885: Bugfix /sys/class/video4linux/videoX/name truncation
The card names are being truncated in the video4linux sys class name file.
Prior to this patch they were shown as:
cx23885[0] mpeg (Hauppauge WinT
cx23885[0] video (Hauppauge WinT
cx23885[0] vbi (Hauppauge WinT

After this patch they are shown as:
Hauppauge WinTV-HVR1850 (video)
Hauppauge WinTV-HVR1850 (mpeg)
Hauppauge WinTV-HVR1850 (vbi)

09b3bc223b [media] cx23885: Control cleanup on the MPEG Encoder
Added three new control calls (g_std, querystd and g_ctrl) to
the -417 driver. Also routed other controls through the main
cx23885 driver meaning that the controls for the 417 and the
raw video device all enter the driver code and are handled
in a single place.

350451375d [media] cx23885: Hauppauge HVR1850 Analog driver support
First in a series of patches that adds support to the cx23885 driver
for CX23888 analog video handling. Raw and MPEG video support is
being added for the HVR1850 driver in the patch, and the following
series of patches.

Some basic cx23885 driver cleanup. Partly to add HVR1850 support
and partly to allow -417.c V4L2 calls to be routed through thr
driver core and handled in a single place.

Make a number of core driver functions available to the -417.c
driver to streamline the driver.

Add the analog tuner ops definition so we can reach/tune the
hardware when we need to. Added the tff field so 888 based cards
(which have a weird field ordering issue) can be accomodated
and worked around in the driver.
