Oliver Endriss d7e7a15678 V4L/DVB (4631): Av7110: remove V4L2_CAP_VBI_CAPTURE flag
Implement fix suggested by Michael Hunold for a bug reported
by Philipp Matthias Hahn: Starting "kdetv" on a Siemens DVB-C 1.x
produced an oops because kdetv opened "/dev/vbi0".
Remove the V4L2_CAP_VBI_CAPTURE flag because it does not work with
this type of hardware anyway.

Christoph Pfister 4e318bef68 V4L/DVB (4501): Add support for knc one dvb-s plus with 1894:0011
Apparently there are two types of knc1 dvb-s plus cards with different tuners 
(as for the knc1 dvb-s ones). This patch adds support for those cards with 
subsystem id 1894:0011.

Patrick Boettcher dea74869f3 V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a pointer field inside dvb_frontend
The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
  always, before you could assign the static pointer directly, which was
  dangerous.

Andrew de Quincey d09dbf92ad V4L/DVB (3762): Add sysfs device links to dvb devices
Currently in /sys/class/dvb/dvbX.demuxY/ we have:
	dev
	uevent
With the patch, we have (for a PCI DVB device):
	dev
	device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:03:0d.0
	uevent
So userspace tools can (finally) work out which physical device a DVB adapter
refers to. Previously you had to kinda look through dmesg and hope that it
hadn't been dumped out of the buffer. This makes debugging a lot easier if
the system has been up for a long time!
This is done by adding an extra 'struct device *' parameter to
dvb_register_adapter(). It will work with any kind of standard
linux 'device'. Additionally, if someone has an embedded system which does
things differently, they can simply supply 'NULL' and the behaviour will be
as before - the link will simply not appear.

Andrew de Quincey 86f40cc3c9 V4L/DVB (3673): Fix budget-av CAM reset
Unfortunately on the budget-av board, the CAM reset line is tied to the
frontend reset line, so resetting the CAM also zaps the frontend. This
breaks the tda1004x at least, and causes it to fail to tune until the
budget-av module is reloaded. This patch adds an exported function to dvb_frontend
that allows a card to forcibly reinitialise a frontend. The budget-av now
does this on CAM reset, which corrects this problem.
since they do not tie the CAM reset line to the frontend reset line.

- Issue a warning when more than 80% of the DMA buffer is being used 
  (probably due to bad IRQ latency). Warnings are rate-limited.
- Introduce a new parameter 'bufsize' (in KByte) which increases the
  default DMA buffer of 188 KByte up to 1410 KByte (Activy: 564 KByte).

Hans Verkuil 301e22d691 V4L/DVB (3584): Implement V4L2_TUNER_MODE_LANG1_LANG2 audio mode
Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER).
This mode allows the user to select both languages of a bilingual transmission,
one language on the left, one on the right audio channel. If there is no
bilingual transmission, or it is not supported, then this mode should act like
V4L2_TUNER_MODE_STEREO.
This mode is introduced for PVR-like drivers where it is useful to be able to
record both languages of a bilingual broadcast.
