With all the v4l2_subdev changes that were made to these drivers it is a
good idea to increase the version number of each driver.
It's just the patch level that is increased, except for the zoran and saa7146
drivers where the minor number was increased due to the more substantial
changes that were made to those two drivers.

Since i2c autoprobing will disappear bttv needs to be converted to use
v4l2_subdev instead.
Without autoprobing the autoload module option has become obsolete. A warning
is generated if it is set, but it is otherwise ignored.
Since the bttv card definitions are of questionable value a new option was
introduced to allow the user to control which audio module is selected:
msp3400, tda7432 or tvaudio (or none at all).
By default bttv will use the card definitions and fallback on tvaudio as the
last resort.
If no audio device was found a warning is printed.
The saa6588 RDS device is now also explicitly probed since it is no longer
possible to autoprobe it. A new saa6588 module option was added to override
the card definition since I suspect more cards have this device than one
would guess from the card definitions.
Note that the probe addresses of the i2c modules are hardcoded in this
driver. Once all v4l drivers are converted to v4l2_subdev this will be
cleaned up. Such data belongs in an i2c driver header.

From: Trent Piepho <xyzzy@speakeasy.org>
The bttv driver had static array of structures for up to 16 possible bttv
devices, even though few users have more than one or two. The structures
were quite large and this resulted in a huge BSS segment.
Change the driver to allocate the bttv device data dynamically, which
changes "struct bttv bttvs[BTTV_MAX]" to "struct bttv *bttvs[BTTV_MAX]".
It would be nice to get ride of "bttvs" entirely but there are some
complications with gpio access from the audio & mpeg drivers.
To help bttvs removal along anyway, I changed the open() methods use the
video device's drvdata to get the driver data instead of looking it up in
the bttvs array. This is also more efficient. Some WARN_ON()s are added
in cases the device node exists by the bttv device doesn't, which I don't
think should be possible.
The gpio access functions need to check if bttvs[card] is NULL now. Though
calling them on a non-existent card in the first place is wrong, but hard
to solve given the fundamental problems in how the gpio access code works.
This patch reduces the bss size by 66560 bytes on ia32. Overall change is a
reduction of 66398 bytes, as the WARN_ON()s add some 198 bytes.

From: Trent Piepho <xyzzy@speakeasy.org>
Over half of the card database was used to store muxsel data. 64 bytes
were used to store one 32 bit word for each of up to 16 inputs.
The Bt8x8 only has two bits to control its mux, so muxsel data for 16
inputs will fit into a single 32 bit word. There were a couple cards that
had special muxsel data that didn't fit in two bits, but I cleaned them up
in earlier patches.
Unfortunately, C doesn't allow us to have an array of bit fields. This
makes initializing the structure more of a pain. But with some cpp magic,
we can do it by changing:
.muxsel = { 2, 3, 0, 1 },
.muxsel = { 2, 2, 2, 2, 3, 3, 3, 3, 1, 1 },
Into:
.muxsel = MUXSEL(2, 3, 0, 1),
.muxsel = MUXSEL(2, 2, 2, 2, 3, 3, 3, 3, 1, 1),
That's not so bad. MUXSEL is a fancy macro that packs the arguments (of
which there can be one to sixteen!) into a single word two bits at a time.
It's a compile time constant (a variadic function wouldn't be) so we can
use it to initialize the structure. It's important the the arguments to
the macro only be plain decimal integers. Stuff like "0x01", "(2)", or
"MUX3" won't work properly.
I also created an accessor function, bttv_muxsel(btv, input), that gets the
mux bits for the selected input. It makes it cleaner to change the way the
muxsel data is stored.
This patch doesn't change the code size and decreases the datasegment by
9440 bytes.

The code was using a muxsel value of -1U to indicate a digital input. A
couple places in were checking of muxsel < 0 to detect this, which doesn't
work of course because muxsel is unsigned and can't be negative.
Only a couple cards had digital inputs and it was always the last one, so
for the card database create a one bit field that indicates the last input
is digital. On init, this is used to set a new field in the bttv struct to
the digital input's number or UNSET for none. This makes it easier to
check if the current input is digital.

The norm value in the driver is an index into an array and the the driver
doesn't allow it to be negative or otherwise invalid. It should be
unsigned but wasn't in all places.
Fix some structs and functions to have the norm be unsigned. Get rid of
useless checks for "< 0". Most of the driver code can't handle a norm
value that's out of range, so change some ">= BTTV_TVNORMS" checks to
BUG_ON(). There's no point in silently ignoring invalid driver state just
to crash because of it later.

PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo.
Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct.
So, to access it, a subroutine call is needed.
This patch renames all occurences of those function calls to be
consistent with the video-buf split.

Due to several internal API changes on kernel, kernel backward
compatibility were lost. Basically, compat.h should be the last include
for it to work properly.
This patch basically reorders kernel headers to allow backward compat to
work fine.
Also:
Some includes were added after some non-include macros, on old drivers.
Better to keep all includes at the beginning of the files.

Adds the missing VIDIOC_CROPCAP, G_CROP and S_CROP ioctls, permitting
applications to capture or overlay a subsection of the picture or to
extend the capture window beyond active video, into the VBI area and the
horizontal blanking. VBI capturing can start and end on any line,
including the picture area, and apps can capture different lines of each
field and single fields.
For compatibility with existing applications, the open() function
resets the cropping and VBI capturing parameters and a VIDIOC_S_CROP
call is necessary to actually enable cropping.
Regrettably in PAL-M, PAL-N, PAL-Nc and NTSC-JP mode the maximum image
width will increase from 640 and 768 to 747 and 923 pixels respectively.
Like the VBI changes however, this should only affect applications which
depend on former driver limitations, such as never getting more than 640
pixels regardless of the requested width.
Also, new freedoms require additional checks for conflicts and some
applications may not expect an EBUSY error from the VIDIOC_QBUF and
VIDIOCMCAPTURE ioctls. These errors should be rare though.
So far, the patch has been tested on a UP machine with a bt878 in PAL-
BGHI and NTSC-M mode using xawtv, tvtime, mplayer/mencoder, zapping/
libzvbi and these tools: http://zapping.sf.net/bttv-crop-test.tar.bz2

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.
