The core driver can now operate in either vmalloc or dma-contig modes;
obviously the latter is preferable when it is supported. Default is
currently vmalloc on all platforms; load the module with buffer_mode=1 for
contiguous DMA mode.

[media] marvell-cam: convert to videobuf2
This is a basic, naive conversion to the videobuf2 infrastructure, removing
a lot of code in the process. For now, we're using vmalloc, which is
suboptimal, but it does match what the cafe driver did before. In the cafe
case, it may have to stay that way just because memory is too tight to do
direct streaming; mmp-camera will be able to do better.

[media] davinci vpbe: VENC( Video Encoder) implementation
This patch adds the VENC or the Video encoder, which is responsible
for the blending of all source planes and timing generation for Video
modes like NTSC, PAL and other digital outputs. the VENC implementation
currently supports COMPOSITE and COMPONENT outputs and NTSC and PAL
resolutions through the analog DACs. The venc block is implemented
as a subdevice, allowing for additional external and internal encoders
of other kind to plug-in.
This patch implements the functionality of the OSD block
of the VPBE. The OSD in total supports 4 planes or Video
sources - 2 mainly RGB and 2 Video. The patch implements general
handling of all the planes, with specific emphasis on the Video
plane capabilities as the Video planes are supported through the
V4L2 driver.

http://www.spinics.net/lists/linux-media/msg33700.html
I'm reverting the removal of this unused ioctl, as it seems that some
drivers under development may be using. So, I'll wait until the next
merge window before removing those unused ioctls, to give a chance for
developers to submit their pending work.
[media] DocBook/video.xml: Document the remaining data structures
Now, all data structures are commented. A few ioctls remain undocumented:
Error: no ID for constraint linkend: VIDEO_GET_SIZE.
Error: no ID for constraint linkend: VIDEO_GET_FRAME_RATE.
Error: no ID for constraint linkend: VIDEO_GET_PTS.
Error: no ID for constraint linkend: VIDEO_GET_FRAME_COUNT.
Error: no ID for constraint linkend: VIDEO_COMMAND.
Error: no ID for constraint linkend: VIDEO_TRY_COMMAND.
The av7110 uses an OSD API. Such API is not documented at all. Also,
the osd.h API uses camelCase and some other weird stuff. Also, dvb-core
doesn't recognize it.
I don't see any good reason why we should document it. It seems better
to just let it as-is. If ever needed, it is probably better to write
a different API for dvb-core.
[media] DocBook/net.xml: Synchronize Network data structure
There's no documentation at all for the DVB net API. Still, better to
remove a few warnings about the missing symbols. So, add the net data
structure inside the net.xml. Now, only the ioctl documentation is missed.
[media] DocBook/demux.xml: Add the remaining data structures to the API spec
Still, there are a few ioctl's not documented:
Error: no ID for constraint linkend: DMX_GET_PES_PIDS.
Error: no ID for constraint linkend: DMX_GET_CAPS.
Error: no ID for constraint linkend: DMX_SET_SOURCE.
Error: no ID for constraint linkend: DMX_ADD_PID.
Error: no ID for constraint linkend: DMX_REMOVE_PID.
[media] Docbook/ca.xml: match section ID's with the reference links
Make sure that both ca.h.xml and ca.xml will match the same names for
the sections/links.
This way, it is now possible to identify API spec gaps:
Error: no ID for constraint linkend: ca-pid.
Error: no ID for constraint linkend: ca-pid.
Error: no ID for constraint linkend: CA_RESET.
Error: no ID for constraint linkend: CA_GET_CAP.
Error: no ID for constraint linkend: CA_GET_SLOT_INFO.
Error: no ID for constraint linkend: CA_GET_DESCR_INFO.

Error: no ID for constraint linkend: CA_SEND_MSG.
Error: no ID for constraint linkend: CA_SET_DESCR.
Error: no ID for constraint linkend: CA_SET_PID.
Basically, in this case, no CA ioctl is described at the specs, and one
file structure (ca-pid) is missing.
[media] dvb/audio.h: Remove definition for AUDIO_GET_PTS
While this ioctl is defined inside dvb/audio.h, it is not docummented
at the API specs, nor implemented on any driver inside the Linux Kernel.
So, it doesn't make sense to keep it here.
As this is not used anywere, removing it is not a regression. So,
there's no need to use the normal features-to-be-removed process.
Although this ioctl is only used at the av7110 driver, it is not
described at the API docbook. Yet, AUDIO_PAUSE ioctl description
somewhat describes it. Fill the gap by using the information there
and by looking inside av7110 implementation.
[media] DocBook/audio.xml: match section ID's with the reference links
Make sure that both audio.h.xml and audio.xml will match the same names.
This way, it is now possible to identify API spec gaps:
Error: no ID for constraint linkend: AUDIO_CONTINUE.
Error: no ID for constraint linkend: AUDIO_GET_PTS.
Error: no ID for constraint linkend: AUDIO_BILINGUAL_CHANNEL_SELECT.
While here, fix the cut-and-paste description error on AUDIO_SET_KARAOKE.

[media] DocBook/frontend.xml: Recomend the usage of the new API
The old way of setting delivery system parameters were to use
an union with specific per-system parameters. However, as newer
delivery systems required more data, the structure size weren't
enough to fit. So, recomend using the DVBS2API instead.
