Hans Verkuil d2f7a1a246 [media] vpif_capture.c: v4l2_device_register() is called too late in vpif_probe()
The function v4l2_device_register() is called too late in vpif_probe().
This meant that vpif_obj.v4l2_dev is accessed before it is initialized
which caused a crash.

This used to work in the past, but video_register_device() is now actually
using the v4l2_dev pointer.

Note that vpif_display.c doesn't have this bug, there v4l2_device_register()
is called at the beginning of vpif_probe.

Jonathan Nieder 27351b139c [media] dw2102: use symbolic names for dw2102_table indices
dw2102_properties et al refer to entries in the USB-id table using
hard-coded indices, as in "&dw2102_table[6]", which means adding new
entries before the end of the list has the potential to introduce bugs
in code elsewhere in the file.

Use C99-style initializers with symbolic names for each index to avoid
this.  This way, other device tables wanting to reuse the USB ids can
use expressions like "&dw2102_table[TEVII_S630]" that do not change as
the entries in the table are reordered.

Lei Wen 48ecf9fe8f [media] soc-camera: change order of removing device
As our general practice, we use stream off before we close
the video node. So that the drivers its stream off function
would be called before its remove function.

But for the case for ctrl+c, the program would be force closed.
We have no chance to call that vb2 stream off from user space,
but directly call the remove function in soc_camera.

In that common code of soc_camera:

                ici->ops->remove(icd);
                if (ici->ops->init_videobuf2)
                        vb2_queue_release(&icd->vb2_vidq);

It would first call the device remove function, then release vb2,
in which stream off function is called. Thus it create different
order for the driver.

This patch change the order to make driver see the same sequence
to make it happy.

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.

Hans de Goede 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.

Hans de Goede 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.

Hans de Goede 5dae603d84 [media] gspca: Check dev->actconfig rather than dev->config
Check dev->actconfig rather than dev->config when checking various
configuration things. dev->config points to the array of configs for the
device so dev->config->foo boils down to dev->config[0].foo and the first
config is not necessarily always the active config.

Hans de Goede 1153f04dea [media] gspca - main: Take numerator into account in fps calculations
In case we ever get sub drivers which do 7.5 fps and express this as
15 / 2 fps.

Hans de Goede d0d3435b21 [media] gspca - main: Correct use of interval in bandwidth calculation
The calculated bandwidth should not be multiplied by the interval, but be
divided by it. Also bInterbval should be interpreted as a power of 2
for isochronous endpoints.

Hans de Goede 66957b8646 [media] gspca - main: rename build_ep_tb to build_isoc_ep_tb
After the "gspca: Fix bulk mode cameras no longer working (regression fix)"
patch build_ep_tb is no longer being called for bulk endpoints.

This patch renames build_ep_tb to build_isoc_ep_tb to make clear it should
only be called for isoc mode cameras.

This patch also:
- drops the no longer needed xfer parameter
- removes a check for bulk mode from the build_isoc_ep_tb code

Jean-François Moine 18bef42c2d [media] gspca - main: Change the bandwidth estimation of isochronous transfer
Having:
- a mean image size of 0.375 time the max compressed image size and
- a frame rate of 30 fps for small images or with USB 2.0/3.0
seems more realistic and gives less image freezes.

Gareth Williams 2a5fc873d6 [media] Add AC97 8384:7650 for some versions of EMP202
Fix detection of EMP202 audio chip. Some versions have an id of
0x83847650 instead of 0xffffffff

Honestech Vidbox NW03 has a EMP202 audio chip with a different Vendor ID.

Apparently, it is the same with the Gadmei ITV380:

Malcolm Priestley 53844c4fc7 [media] it913x add support for IT9135 9006 devices
Support for IT1935 9006 devices.

9006 have version 2 type chip.

9006 devices should use dvb-usb-it9135-02.fw firmware.

On the device tested the tuner id was set to 0 which meant
the driver used tuner id 0x38. The device functioned normally.
