The original patch description, from Randy Dunlap
<randy.dunlap@oracle.com>:
header cleaning: don't include smp_lock.h when not used
Remove includes of <linux/smp_lock.h> where it is not used/needed.
Suggested by Al Viro.
Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

Simplify the VIDIOC_G_CHIP_IDENT implementation by adding a single
common function. The ident can now also return NONE: not found, UNKNOWN:
found, but we don't know what chip it is, and AMBIGUOUS: multiple
chips were matched so the match values were too general.

VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be
used to detect which chips are on the board and based on that information
selected register dumps can be made, making it easy to debug complicated
media chips containing tens or hundreds of registers.
This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl.

The chip matching in struct v4l2_register was rather primitive. It could
not be extended to other busses besides i2c and it lacked a way to
differentiate between two i2c chips driven by the same driver on one
board (e.g. a PVR500 with two tuner chips, one for analog TV and one for
radio).
It has now been improved making it much more powerful.

Added VIDIOC_INT_G_STD_OUTPUT and VIDIOC_INT_S_STD_OUTPUT to allow drivers
to set the TV standard for video output separately from the video capture.
This is needed for cx23415 support where the decoder is separate from the
encoder and can have a different TV standard.
Modified the saa7127 module to listen to VIDIOC_INT_G/S_STD_OUTPUT instead
of VIDIOC_G/S_STD.

Add -include linux/version.h to the cflags. Now code can have backward
compatibility test without including compat.h first.
Linux headers included from compat.h are removed, so that code will get
the same headers when compiling in v4l-dvb as it does in the kernel.
Many drivers have compat.h moved to the end of their include list, as
this lets compat.h do things it can't do at the beginning. Such as test
of something is defined to include compat code, or to put a wrapper
around a function without changing the function's name.

The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such. Officially export them.
VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h
to videodev2.h.
Types used in struct v4l2_register are changed to the userspace
exportable versions (u32 -> __u32, etc).
Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move
the check into the video_ioctl2() dispatcher so it doesn't need to be
duplicated in each driver's call-back function.
CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2).

There's a problem, pointed by Meelis Roos <mroos@linux.ee>, that, on ppc32 arch,
with some gcc versions (noticed with prerelease 4.1.2 20061115), compilation
fails, due the lack of __ucmpdi2 to do the required 64-bit comparision.

video_ioctl2 will auto-generate standard entries at ENUM_FMT.
Also, now, a driver may return a subset of the video array at
the return, to be stored as the current_norm.
For example, a driver may ask for V4L2_STD_PAL. At return,
driver may change it to V4L2_STD_PAL_B. This way, a futher call
to G_STD will return the exact detected video std.

Control processing is often duplicated in the various drivers. Unfortunately,
simple things like the names of controls are often different between drivers,
even though it is the same controls. Adding in the new extended controls and
the need for having control helper functions became apparent.
Several functions have now been added to v4l2-common to do things like
filling the v4l2_queryctrl and v4l2_querymenu structs, to check for
valid control input and to move to the next control when enumerating
over all controls.

Some saa7115-based cards use a different crystal frequency and a different
audio clock generation. Add a new VIDIOC_INT_S_CRYSTAL_FREQ command to be
able to set these values.
Also change the default APLL setting to 0. It makes no sense to have the
audio clock independent from the video clock, this can lead to audio/video
synchronization problems. Setting this to 0 is also consistent with the old
saa7114.c source and the way the Hauppauge Windows driver sets it.

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.

- Moved MSP_SET_MATRIX to v4l2-common.h
- Fix typos and integer overflows in tea5767.c
- Split old freq field into a tv_freq and a radio_freq. Prevents
that a radio tuner is initialized with a tv frequency or vice versa.
- When switching to radio mode initialize the tuner with the last
used radio frequency (this was already done for the TV mode).
As a result of these changes the tuner module now remembers the
last set radio and TV frequencies, which is what you would expect
to happen.
- Move out of range frequencies to the closest valid frequency as per
v4l2 API spec.
- Fix incorrect initial radio frequency (multiplier is 16000, not 16)
- Add boundary check for out of range frequencies.
- Use new flag to check if the order of the CB and freq. depends on
the last set frequency. That is needed for some tuners or you can
get static as a result. The flag is added for those tuners where I know
that the datasheet indicates that this is necessary.
- For this new check use the last set div value, not the last frequency
as radio frequencies are always much higher due to the 16000 multiplier.
