This is the display driver for Texas Instruments's DM644X family
SoC. This patch contains the main implementation of the driver with the
V4L2 interface. The driver implements the streaming model with
support for both kernel allocated buffers and user pointers. It also
implements all of the necessary IOCTLs necessary and supported by the
video display device.

Telling the user they can disable an option if they want is not the
much useful. Describe what it is good for instead.

flush_scheduled_work() is deprecated and scheduled to be removed.
technisat-usb2 already sync-cancels the only work item it uses and
there's no reason for it to call flush_scheduled_work(). Don't use

Mark the alsa stream with SNDRV_PCM_INFO_BATCH,
as the timing to get audio streams can vary.
Also, add SNDRV_PCM_TRIGGER for pause/release.
while here, fix the stop indicator, to be sure that audio
will be properly released at the stop events.

If the audio stream fails for any reason, it should:
1) Report an error via dmesg;
2) Mark internally that the stream didn't started.

Export ac97 volume controls via mixer.
Pulseaudio will probably handle it very badly, as it has
no idea about how volumes are wired, and how are they
associated with each TV input. Those wirings are
card model dependent, and we don't have the wiring mappings
for each supported device.

There are still 3 cases at em28xx-alsa, were those vars should

Depending on the controller, the ov7670 sensor may be told to work with a
different clock speed or to use the SMBUS protocol. Remove the wired-in
code and pass that information from the platform layer. The Cafe driver
now just assumes it's running on an OLPC XO 1; I do not believe it has ever
run anywhere else.

There will eventually be multiple users of the core camera controller, so
separate it from the bus/platform/i2c stuff. I've tried to do the minimal
set of changes to get the driver functioning in this configuration; I did
clean up a bunch of old checkpatch gripes in the process. This driver
works like the old one did on OLPC XO 1 systems.

The patch utility doesn't work with non-binary files. This causes some
tools to break, like generating tarball targets and the scripts that
generate diff patches at http://www.kernel.org/pub/linux/kernel/v2.6/.
So, let's convert all binaries to ascii using base64, and add a
logic at Makefile to convert them back into binaries at runtime.

I'm reverting the removal of this unused ioctl, as it seems that some
drivers under development may be using. So, I'll wait until the next
merge window before removing those unused ioctls, to give a chance for
developers to submit their pending work.

The av7110 uses an OSD API. Such API is not documented at all. Also,
the osd.h API uses camelCase and some other weird stuff. Also, dvb-core
doesn't recognize it.
I don't see any good reason why we should document it. It seems better
to just let it as-is. If ever needed, it is probably better to write
a different API for dvb-core.
