Guennadi Liakhovetski fff96b6685 [media] V4L: soc_camera_platform: do not leave dangling invalid pointers
The life-time of soc-camera device objects can be longer, than the
time, it is attached to a client driver, therefore all references to
the driver own data have to be cleared, when the driver is detached.

Guennadi Liakhovetski 3dcc731a93 [media] V4L: soc-camera: split a function into two
The soc_camera_power_set() function processes two cases: power on anf off.
These two cases don't share and common code, and the function is always
called with a constant power on / off argument. Splitting this function
into two removes a condition check, reduces indentation levels and makes
the code look cleaner.

Guennadi Liakhovetski 489759c0ca [media] V4L: sh_mobile_ceu_camera: the host shall configure the pipeline
It is a task of the host / bridge driver to bind single subdevices into a
pipeline, not of respective subdevices. Eventually this might be handled
by the Media Controller API.

Prepare the mx3_camera friver to support the new VIDIOC_CREATE_BUFS and
VIDIOC_PREPARE_BUF ioctl()s. The .queue_setup() vb2 operation must be
able to handle buffer sizes, provided by the caller, and the
.buf_prepare() operation must not use the currently configured frame
format for its operation, which makes it superfluous for this driver.
Its functionality is moved into .buf_queue().

Mauro Carvalho Chehab 4860c73804 staging: Move media drivers to staging/media
In practice, it is being hard to distinguish when a patch
should go to staging tree or to the media tree. Better
to distinguish it, by putting the media drivers at a
separate staging directory. Newer staging drivers that include
anything with "dvb*.h", "v4l2*.h" or "videodev2.h" should
go to the drivers/staging/media tree.

The ADV7175A/ADV7176A can operate in either 8-bit or 16-bit YCrCb mode.

* 8-Bit YCrCb Mode
This default mode accepts multiplexed YCrCb inputs through
the P7-P0 pixel inputs. The inputs follow the sequence Cb0, Y0
Cr0, Y1 Cb1, Y2, etc. The Y, Cb and Cr data are input on a
rising clock edge.

* 16-Bit YCrCb Mode
This mode accepts Y inputs through the P7–P0 pixel inputs and
multiplexed CrCb inputs through the P15–P8 pixel inputs. The
data is loaded on every second rising edge of CLOCK. The inputs
follow the sequence Cb0, Y0 Cr0, Y1 Cb1, Y2, etc.

This patch fixes incorrect return value. Errors should be returned
as negative numbers.

Mauro Carvalho Chehab 1c5c50685a [media] em28xx: implement VIDIOC_ENUM_FRAMESIZES
Pidgin uses gstreamer (and libv4l) to work. Without implementing this ioctl,
it won't detect properly the size range, and driver will fail.

So, this patch is required, in order to use an em27xx webcam, like
Silvercrest.

The pigdin/gstreamer/libv4l needs to be fixed, as it shouldn't assume
that all drivers will implement this optional ioctl, but, at least now,
devices with em28xx have a better chance of working with pidgin.

Steven Toth a461e0ad3d [media] cx23885: Stop the risc video fifo before reconfiguring it
Safety reasons. We shouldn't be trying to reconfigure a risc
processor instruction queue unless it's stopped.

Steven Toth 19696f09da [media] cx23885: Avoid incorrect error handling and reporting
Previous driver over-reported errors and stopped the video fifo
(causing video to stop) if 1) A risc error occured 2) The risc processor
detected that it has missing lines in the video frame 3) The risc fifo
is about to overflow.

The previous driver reported all three of these cases as risc errors
when this is technically not correct. So, the function was cleaned up.

1. Ensure that risc opcode related errors are correctly shown as such,
   and not overly reported for non-risc-opcode cases.
2. Ensure that line sync and overflow errors are not reported as opcode errors.
3. Ensure that only the risc-op-code case can stop the fifo and dump channel
   / risc processor information.

The net result is that if video becomes unstable, cable disconnect, this will
not trigger a stop of the video firmware (due to missing lines errors).

Steven Toth d44aa2d7fc [media] cx23885: Avoid stopping the risc engine during buffer timeout
1. Removed the verbose 'dump channel state to console', very noisy in
   weak signal conditions.
2. No need for the video buffer timeout to stop the risc engine here.
   Clearer and easier to maintain if start_video_dma() is the single
   place that this is done.
