media: au0828: fix enable and disable source audio and video inconsistencies

2019-04-22T15:22:30+00:00

Enable and disable source interfaces aren't consistent in enforcing
how video and audio share the tuner resource.

Fix these issues to enforce the following rules and allow
sharing between audio and video applications.

- When DVB is streaming, audio/video/vbi/s-video/composite
  should find the resource busy. DVB holds the tuner in
  exclusive mode.
- When video/VBI is streaming, audio can share the tuner and vice versa.
- v4l2 allows multiple applications to open video device.
- Video applications call enable source multiple times during their
  run-time. Resource should stay locked until the last application
  releases it.
- A shared resource should stay in shared state and locked when it is
  in use by audio and video. More than one video application is allowed
  to use the tuner as long as video streaming protocol allows such usage.
  Resource is released when the last video/audio application releases it.
- S-Video and Composite hold the resource in exclusive mode.

media: change au0828 to use Media Device Allocator API

2019-04-22T15:19:05+00:00

Media Device Allocator API to allows multiple drivers share a media device.
This API solves a very common use-case for media devices where one physical
device (an USB stick) provides both audio and video. When such media device
exposes a standard USB Audio class, a proprietary Video class, two or more
independent drivers will share a single physical USB bridge. In such cases,
it is necessary to coordinate access to the shared resource.

Using this API, drivers can allocate a media device with the shared struct
device as the key. Once the media device is allocated by a driver, other
drivers can get a reference to it. The media device is released when all
the references are released.

Change au0828 to use Media Device Allocator API to allocate media device
with the parent usb struct device as the key, so it can be shared with the
snd_usb_audio driver.

Make vb2_ops const as they are only stored in the const field of a
vb2_queue structure. Make the declarations const too.

[media] au0828: Add timer to restart TS stream if no data arrives on bulk endpoint

2017-06-06T10:52:20+00:00

For reasons unclear, we intermittently see a case where the tune
is successful but the bulk stream fails to deliver any packets.

Add a timer to automatically stop/start the data pump if we
encounter such a case.

[media] media: Drop FSF's postal address from the source code files

2017-01-27T13:38:09+00:00

Drop the FSF's postal address from the source code files that typically
contain mostly the license text. Of the 628 removed instances, 578 are
outdated.

The patch has been created with the following command without manual edits:

git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \
	drivers/media/ include/media|while read i; do i=$i perl -e '
open(F,"< $ENV{i}");
