This is a basic, naive conversion to the videobuf2 infrastructure, removing
a lot of code in the process. For now, we're using vmalloc, which is
suboptimal, but it does match what the cafe driver did before. In the cafe
case, it may have to stay that way just because memory is too tight to do
direct streaming; mmp-camera will be able to do better.

This patch adds the VENC or the Video encoder, which is responsible
for the blending of all source planes and timing generation for Video
modes like NTSC, PAL and other digital outputs. the VENC implementation
currently supports COMPOSITE and COMPONENT outputs and NTSC and PAL
resolutions through the analog DACs. The venc block is implemented
as a subdevice, allowing for additional external and internal encoders
of other kind to plug-in.

This patch implements the functionality of the OSD block
of the VPBE. The OSD in total supports 4 planes or Video
sources - 2 mainly RGB and 2 Video. The patch implements general
handling of all the planes, with specific emphasis on the Video
plane capabilities as the Video planes are supported through the
V4L2 driver.

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.

Export ac97 volume controls via mixer.
Pulseaudio will probably handle it very badly, as it has

card model dependent, and we don't have the wiring mappings
for each supported device.

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

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.
