Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media 

Pull media updates from Mauro Carvalho Chehab:
 "This is the first part of the media patches for v3.6.

  This patch series contain:
   - new DVB frontend: rtl2832
   - new video drivers: adv7393
   - some unused files got removed
   - a selection API cleanup between V4L2 and V4L2 subdev API's
   - a major redesign at v4l-ioctl2, in order to clean it up
   - several driver fixes and improvements."

Why: Unsupported/unmaintained/unused since 2.6
----------------------------
What: V4L2 selections API target rectangle and flags unification, the
following definitions will be removed: V4L2_SEL_TGT_CROP_ACTIVE,
V4L2_SEL_TGT_COMPOSE_ACTIVE, V4L2_SUBDEV_SEL_*, V4L2_SUBDEV_SEL_FLAG_*
in favor of common V4L2_SEL_TGT_* and V4L2_SEL_FLAG_* definitions.
For more details see include/linux/v4l2-common.h.
When: 3.8
Why: The regular V4L2 selections and the subdev selection API originally
defined distinct names for the target rectangles and flags - V4L2_SEL_*
and V4L2_SUBDEV_SEL_*. Although, it turned out that the meaning of these
target rectangles is virtually identical and the APIs were consolidated
to use single set of names - V4L2_SEL_*. This didn't involve any ABI
changes. Alias definitions were created for the original ones to avoid
any instabilities in the user space interface. After few cycles these
backward compatibility definitions will be removed.

v4l2_file_operations and locking
--------------------------------
ioctls and locking
------------------
You can set a pointer to a mutex_lock in struct video_device. Usually this
will be either a top-level mutex or a mutex per device node. By default this
lock will be used for unlocked_ioctl, but you can disable locking for
selected ioctls by calling:
The V4L core provides optional locking services. The main service is the
lock field in struct video_device, which is a pointer to a mutex. If you set
this pointer, then that will be used by unlocked_ioctl to serialize all ioctls.
void v4l2_disable_ioctl_locking(struct video_device *vdev, unsigned int cmd);
If you are using the videobuf2 framework, then there is a second lock that you
can set: video_device->queue->lock. If set, then this lock will be used instead
of video_device->lock to serialize all queuing ioctls (see the previous section
for the full list of those ioctls).
E.g.: v4l2_disable_ioctl_locking(vdev, VIDIOC_DQBUF);
The advantage of using a different lock for the queuing ioctls is that for some
drivers (particularly USB drivers) certain commands such as setting controls
can take a long time, so you want to use a separate lock for the buffer queuing
ioctls. That way your VIDIOC_DQBUF doesn't stall because the driver is busy
changing the e.g. exposure of the webcam.
You have to call this before you register the video_device.
Of course, you can always do all the locking yourself by leaving both lock
pointers at NULL.
Particularly with USB drivers where certain commands such as setting controls
can take a long time you may want to do your own locking for the buffer queuing
ioctls.
If you want still finer-grained locking then you have to set mutex_lock to NULL
and do you own locking completely.
It is up to the driver developer to decide which method to use. However, if
your driver has high-latency operations (for example, changing the exposure
of a USB webcam might take a long time), then you might be better off with
doing your own locking if you want to allow the user to do other things with
the device while waiting for the high-latency command to finish.
If a lock is specified then all ioctl commands will be serialized on that
lock. If you use videobuf then you must pass the same lock to the videobuf
queue initialize function: if videobuf has to wait for a frame to arrive, then
it will temporarily unlock the lock and relock it afterwards. If your driver
also waits in the code, then you should do the same to allow other processes
to access the device node while the first process is waiting for something.
If you use the old videobuf then you must pass the video_device lock to the
videobuf queue initialize function: if videobuf has to wait for a frame to
arrive, then it will temporarily unlock the lock and relock it afterwards. If
your driver also waits in the code, then you should do the same to allow other
processes to access the device node while the first process is waiting for
something.
In the case of videobuf2 you will need to implement the wait_prepare and
wait_finish callbacks to unlock/lock if applicable. In particular, if you use
the lock in struct video_device then you must unlock/lock this mutex in
wait_prepare and wait_finish.
wait_finish callbacks to unlock/lock if applicable. If you use the queue->lock
pointer, then you can use the helper functions vb2_ops_wait_prepare/finish.
The implementation of a hotplug disconnect should also take the lock before
calling v4l2_device_disconnect.
The implementation of a hotplug disconnect should also take the lock from
video_device before calling v4l2_device_disconnect. If you are also using
video_device->queue->lock, then you have to first lock video_device->queue->lock
followed by video_device->lock. That way you can be sure no ioctl is running
when you call v4l2_device_disconnect.

V4L core support for video capture and overlay devices, webcams and
AM/FM radio cards.
This kernel includes support for the new Video for Linux Two API,
(V4L2).
Additional info and docs are available on the web at
<http://linuxtv.org>
Documentation for V4L2 is also available on the web at
<http://bytesex.org/v4l/>.
To compile this driver as a module, choose M here: the
module will be called videodev.

Enable this if you own a DVB/ATSC adapter and want to use it or if
you compile Linux for a digital SetTopBox.
Say Y when you have a DVB or an ATSC card and want to use it.
