51a99c0428 V4L/DVB (6049): ivtv: fix VBI reinsertion decoding
- Invalid VBI packets should result in an empty VBI frame, not
  in an zero-sized frame that causes the reader to incorrectly
  return a 0 (EOF) value.
- PIO completion should not reset the sg_pending_size field.
- The DMA offset detection code should be ignored for PIO transfers:
  it somehow messes up the data on the card and is not needed anyway
  for PIO.

37093b1ea6 V4L/DVB (6047): ivtv: Fix scatter/gather DMA timeouts
It turns out that the cx23415/6 DMA engine cannot do scatter/gather DMA
reliably. Every so often depending on the phase of the moon and your
hardware configuration the cx2341x DMA engine simply chokes on it and
you have to reboot to get it working again.

This change replaced the scatter/gather DMA by single transfers at a time,
where the driver is now responsible for DMA-ing each buffer.

UDMA is still done using scatter/gather DMA, that will be fixed soon.

Many thanks to Mark Bryars <mark.bryars@etvinteractive.com> for discovering
the link between scatter/gather and the DMA timeouts.

f4071b85ea V4L/DVB (6046): ivtv: always steal full frames if out of buffers.
When there are no more free buffers, then buffers are stolen from the
predma queue. Buffers should be stolen from the head of that queue (which
is where the most recently added buffers are) and all buffers belonging
to a frame should be stolen. Otherwise 'half-frames' would remain in the
queue, which leads to ugly playback and complete sync failure for YUV
buffers.

3562c43be8 V4L/DVB (6045): ivtv: fix handling of INITIALIZE_INPUT fw call
The CX2341X_ENC_INITIALIZE_INPUT firmware call requires careful handling,
otherwise the computer can freeze or the top-third of the screen can start
flickering. This patch ensures that CX2341X_ENC_INITIALIZE_INPUT is called
at the right time and in the right way.

In addition the stop capture handling was improved so that the last pending
DMA transfer is also processed. Otherwise this would be the first data that
arrived when a new capture was started which is not what you want.

fa40b2237a V4L/DVB (6034): cx88: Add parameter to control radio deemphasis time constant
FM radio transmission use a preemphasis/deemphasis scheme to reduce
high-frequency noise.  The cx88 audio decoder is supposedly set to no
deemphasis by the current driver.

However, the "no deemphasis" setting doesn't work.  On my chip, cx23883, it
produces the same result as the 75 us time constant.  Maybe the default
settings on the cx23881 are for 50 us?

Since the deemphasis time constant varies by country, allow setting it via a
module parameter.

5772f81326 V4L/DVB (6023): cx88: Clean up some ugly and inconsistent printk()s
Get rid of the "CORE" prefix from cx88 printks.  It was only used a few times,
and it makes it look like they're coming from the kernel core or something.

Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a
"cx88[0]" prefix to be consistent, and to keep people who grep their dmesg
output for cx88 from missing it.  Get rid of the addresses, which are always
wrong.  The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.

In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from
the cx8802 driver.

Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for
KERN_INFO and KERN_ERR messages.

The changed printks in cx88-mpeg.c also needed lots of whitespace and
80-column fixes.

A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels
or a consistent "cx88[?]/2" or "cx88[?]/0" prefix.

bbc83597df V4L/DVB (6022): cx88: Move card core creation from cx88-core.c to cx88-cards.c
A lot of code in cx88-cards.c was only used by cx88-core.c when the core state
is first allocated and initialized.  Moving that task to cx88-cards makes the
driver simpler and the files more self contained.

- Module parameters tuner, radio, card, and latency move to cx88-cards.c
- cx88_boards is made static
- cx88_subids is made static and const
- cx88_bcount is eliminated
- cx88_idcount is eliminated
- cx88_card_list() is made static
- cx88_card_setup_pre_i2c() is made static
- cx88_card_setup() is made static
- cx88_pci_quirks() is moved from cx88-core to cx88-cards
  The function argument "char *name" is made const too
- get_ressources() is moved from cx88-core to cx88-cards, and renamed to
  cx88_get_resources()
- The code to allocate and initialize the core state struct and the chip is
  moved out of cx88-core.c:cx88_get_core() and into a new function in
  cx88-cards.c, cx88_core_create().  This makes both functions simpler.

6a59d64c5c V4L/DVB (6021): cx88: Copy board information into card state
The cx88 driver state stored the ID of the board type in core->board.  Every
time the driver need to get some information about the board configuration, it
uses the board number as an index into board configuration array.

This patch changes it so that the board number is in core->boardnr, and
core->board is a copy of the board configuration information.  This allows
access to board information without the extra indirection.  e.g.
cx88_boards[core->board].mpeg becomes core->board.mpeg.

This has a number of advantages:
- The code is simpler to write.

- It compiles to be smaller and faster, without needing the extra array lookup
  to get at the board information.

- The cx88_boards array no longer needs to be exported to all cx88 modules.

- The boards array can be made const

- It should be possible to avoid keeping the (large) cx88_boards array around
  after the module is loaded.

- If module parameters or eeprom info override some board configuration
  setting, it's not necessary to modify the boards array, which would
  affect all boards of the same type.

Audio muting for the tuner input was implemented by stopping the

It's rare and seems to happen with NTSC only.

It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

a18255bef2 V4L/DVB (5985): Fix the min/max frequencies of some DVB-C frontends
The min frequencies of the DVB-C frontends are wrong. 

In Europe, the center frequency of the lowest channel is 50.5MHz and not 
51MHz. All known cards with the stv0297/tda0002x/ves1820 frontend are 
able to tune to this frequency.

I've changed the range to the lowest channel - 1/2 bandwidth and the 
highest channel + 1/2 bandwidth. For the design of the dvb driver, the 
frequency ranges must be part of the tuner and not of the frontend 
itself. The same frontend may be used for different tuners. 

The attached patch does only fix the ranges and not the design.

5e082f1521 V4L/DVB (5978): tuner: Better tuner radio support
Add radio support for the Thomson DTT7612 tuner.

This tuner uses a different 1st intermediate frequency than the other radio
tuners supported (a lot of NTSC radio tuners probably need this change too).

Add a new tuner-simple parameter, radio_if.  It selects the 1st IF used for
radio reception.  The radio frequency setting code in tuner-simple now uses
this field, instead of a special case select() block for each tuner with radio
support.

The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1
in tuner-types.c.

The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and
fm_gain_normal = 1.

Add some defines for tda9887 bits that control IF setting in radio mode.

Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz
radio IF.

Fix the way tda9887 radio options work.  The driver was modifying the default
radio mode config templates based on the TDA9887_XXXX flags.  This means that
_all_ tuners would get the same settings.  If you had a one tuner than used
TDA9887_GAIN_NORMAL and one that didn't, both would get the setting.  Now the
tda9987 driver just checks if tuner mode is radio and then applies the config
settings directly to the data being sent, just like how all the TV mode
settings already work.

The PLL setting math is made a little more accurate.

And a grammar error in a printk is fixed.

19dc74b7c5 V4L/DVB (5975): cx88: Wrong values used for HD-3000 radio mode
After some tedious work with a logic probe and a magnifying glass, I've
determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz
IF output on pin 12 and the FM 10.7MHz If output on pin 11.  GPIO 2 is used to
switch the card's analog sound output from from the analog input connector to
the CX23883's audio DACs.

So, in radio mode GPIO2 = 1 and GPIO7 = 0.

Add some comments about how the HD-3000's GPIOs are connected.

Delete the vmux setting for the radio, as vmux doesn't apply to radio mode.
Also delete the lines setting unused gpio words to zero; it's not necessary as
0 is the default value for uninitialized fields.

bfd7beacff V4L/DVB (5973): ivtv: attach yuv field order to each frame
In the current driver, the field order is global. As soon as it's changed it
takes immediate effect. This is a problem when the video changes order mid
stream. Although it mostly works okay, the video may judder / flicker.

This patch attaches the field order to the frame, so that any buffered frames
will not be displayed until the correct field. In the event that the field
order is changed mid stream, the driver will ensure that the previous frame
is displayed for a minimum of 3 fields. These are the two original fields the
frame should have occupied, plus the one extra since the new frame still has
to wait for the correct field.

943e8910db V4L/DVB (5972): ivtv: prevent yuv register updates from being missed
The yuv output code always compares the new frame position & size with those
of the previous frame. If they are different, a flag is set to request the
yuv output registers be updated when the new frame is displayed.

If the incoming frames are delivered too fast, exhausting the buffers, the
most recent frame already buffered will be discarded. Unfortunately, any
update request will also be discarded. If the new frame matches the size &
position of the now discarded frame, the yuv registers are not flagged for
update & will remain in their old state.

This patch preserves the register update flag in the event that a frame is
dropped.

32db775452 V4L/DVB (5902): Add ivtv-fb framebuffer driver.
Add the ivtv-fb framebuffer driver for cx23415 devices (currently
only the Hauppauge PVR-350 cards). This makes it possible to use
the On-Screen Display functionality of these cards, either for menus
during MPEG playback, or as a console or X display.

60e3cac47a V4L/DVB (5885): zr36067: Fix problems with module parameters
Add permissions to all the module parameters so they can be queried and set
(when possible) via sysfs.

Add description for the vidmem parameter.

Change the video_nr parameter to an array, so that the video number can be
specified when a user has more than one card.  The driver would try to give
all cards the same number otherwise, which will fail for all cards after the
first.

The default_input option would only allow values of 0 or 1, contrary to the
description.  Allow values up to the number of inputs defined for the card.

Add description of lock_norm's different behavior for 1 and >1.

18b548ca58 V4L/DVB (5884): zr36067: clean up debug function
Debugging cleanups to the zr36067 driver:

* Use module_param_named() to declare the debug parameter, so we can
  use a single global variable to handle the debug level. This makes
  the driver a bit smaller (by 648 bytes on x86_64), thanks to one
  less level of indirection on every use.

* Change the debug parameter sysfs permissions, so that the debug
  level can be adjusted at runtime, as is done in many other
  media/video drivers.

* The debug level is between 0 and 5, not 0 and 4.

* Move the zr_debug export and dprintk macro definition to a header
  file so that we don't have to define them in each source file.

* Simplify a duplicate test on zr_debug.

Note that zr_debug was subsequently renamed to debug_zr36067 to avoid
possible conflicts with other Zoran device drivers, on a suggestion
by Trent Piepho.

9b5d0f1e6d V4L/DVB (5862): V4L: Add internal ioctl-like interface.
This patch adds an internal ioctl-like interface which can be used in
situations where a single Video4Linux device is implemented by multiple
device drivers. One master device controls one or more slave devices.
The slaves provide Video4Linux ioctl-like interface for the use of the
master.

Only a handful of ioctls are implemented at the moment. More can (and
should) be added as more functionality is required.
