861018a6a9 V4L/DVB (3971): Cx88-blackbird: use standard filename for cx23416 firmware
cx88-blackbird uses the same encoder firmware for the cx23416 chip that is
used by ivtv and pvrusb2.
This patch alters the driver to expect the cx23416 encoder firmware to be
located in the file, "v4l-cx2341x-enc.fw", instead of using
"blackbird-fw-enc.bin"

01a9cd99cf V4L/DVB (3817): KWorld HardwareMpegTV XPert: set encoder video standard based on tvnorm
The KWorld HardwareMpegTV XPert uses a multistandard tuner, tda8290 + tda8275.
Without checking the video standard in blackbird_probe, the encoder defaults
to PAL, even if the incoming video stream is NTSC. This patch checks the video
standard set by the cx2388x decoder, and sets the encoding height and frame
accordingly.
This patch is designed to only affect the KWorld HardwareMpegTV XPert.

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.

It looks like the HD3000 was prototyped with the 7610 tuner when

  but production versions used a DTT7612 tuner.
- This patch changes both dvb-pll settings and V4L tuner type.

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.

8bf2f8e747 V4L/DVB (3577): Cleanup audio input handling
Cleanup audio input handling in bttv and tvaudio:
- inputs were specified that were never used
- mute was handled as a special input which led to confusing code
- confusing naming made it difficult to see if the setting was for
  i2c or gpio.
The old audiochip.h input names moved to tvaudio.h. Currently this
is used both by tvaudio and msp3400 until the msp3400 implements the
new msp3400-specific inputs.
Detect in bttv the tvaudio and msp3400 i2c clients and use these
client pointers to set the inputs directly instead of broadcasting the
command.
Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be
replaced again later by the new ROUTING commands.
Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is
a user level command and not to be used internally. It wasn't called at
all anyway.

When cx88-alsa was added to cx88/Kconfig, it was added in between

undesireable effects to the appearance of the menu options in

and restore the correct menuconfig appearance.

Add support for the FE6600 tuner used on the DVB-T Hybrid board.
Add support for the Zarlink ZL10353 DVB-T demodulator, which supersedes the
MT352, used on the DViCO FusionHDTV DVB-T Hybrid and later model Plus boards.

4a287cfeea V4L/DVB (3394): Bttv: correct bttv_risc_packed buffer size
This patch fixes the strange crashes I was seeing after using
bttv card, caused by a buffer overflow in bttv_risc_packed.
The instruction buffer size calculation contains two errors:
(a) a non-zero padding value can push the start of the next bpl
section to just before a page border, leading to more scanline
splits and thus additional instructions.
(b) the first DMA region can be smaller than one page, so there can
be a scanline split even if bpl*lines is smaller than PAGE_SIZE.
For example, consider the case where offset is 0, bpl is 2, padding
is 4094, lines is smaller than 2048, the first DMA region has size 1
and all others have size PAGE_SIZE, assumed to equal 4096.  Then
all bpl regions cross page borders and the number of instructions
written is 2*lines+2, rather than lines+2 (the current estimate).
With this patch the number of instructions for this example is
estimated to be 2*lines+3.
Also, the BUG_ON that was supposed to catch buffer overflows contained
a thinko causing it fire only if the buffer was overrun by a factor of
16 or more, so it fixes the the BUG_ON's (using sizeof rather than "4").

6457af5f7e V4L/DVB (3393): Cx88: reduce excessive logging
- fix temporary debug code by changing printk to dprintk at level 1.
- move CORE_IOCTL messages from level 1 to level 2.
- this should help with selective debugging,
  while not filling people's logs up during normal use.

f29edc2210 V4L/DVB (3368): KWorld HardwareMpegTV XPert: update comments
Standard video using the cx88 broadcast decoder is
working, but blackbird isn't working yet, audio is only
working correctly for television mode. S-Video and Composite
are working for video-only, so I have them disabled for now.
