Add a driver for the video capture port on VIA integrated chipsets. This
version has a remaining OLPCism or two and expects to be talking to an
ov7670; those can be improved as the need arises.

This patch provides a V4L2 SoC Camera driver for OV6650 camera sensor, found
on OMAP1 SoC based Amstrad Delta videophone.
Since I have no experience with camera sensors, and the sensor documentation I
was able to find was not very comprehensive, I left most settings at their
default (reset) values, except for:
- those required for proper mediabus parameters and picture geometry and
format setup,
- those used by controls.
Resulting picture quality may be far from perfect, but better than nothing.
In order to be able to get / set the sensor frame rate from userspace, I
decided to provide two not yet SoC camera supported operations, g_parm and
s_parm. These can be used after applying patch 4/6 from this series,
"SoC Camera: add support for g_parm / s_parm operations".
Created and tested against linux-2.6.36-rc5 on Amstrad Delta.

This is a V4L2 driver for TI OMAP1 SoC camera interface.
Both videobuf-dma versions are supported, contig and sg, selectable with a
module option. The former uses less processing power, but often fails to
allocate contignuous buffer memory. The latter is free of this problem, but
generates tens of DMA interrupts per frame. If contig memory allocation ever
fails, the driver falls back to sg automatically on next open, but still can
be switched back to contig manually. Both paths work stable for me, even
under heavy load, on my OMAP1510 based Amstrad Delta videophone, that is the
oldest, least powerfull OMAP1 implementation.
The interface generally works in pass-through mode. Since input data byte
endianess can be swapped, it provides up to two v4l2 pixel formats per each of
several soc_mbus formats that have their swapped endian counterparts.
Boards using this driver can provide it with the following platform data:
- if and what freqency clock is expected by an on-board camera sensor,
- what is the maximum pixel clock that should be accepted from the sensor,
- what is the polarity of the sensor provided pixel clock,
- if the interface GPIO line is connected to a sensor reset/powerdown input
and what is the input polarity.

The driver author seems to not worked on this driver since its conversion
from 2.2 to 2.4. Nobody is known to have a stradis hardware for testing. As
it still uses V4L1 API, BKL and probably some other old stuff, someone would
need to work on it to preserve the driver. Instead of investing time and
efforts to keep porting it to work with new API's, it seems better to just
drop the driver.
So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody
cares enough to port parallel port support to gspca or to create a new driver
that uses the same gspca-cpia sub-driver.

cpia driver were re-written inside gspca driver, for USB devices. The only
functionality that were not migrated is the support for parallel port,
as:
1) the developer didn't find any hardware;
2) it doesn't seem important to keep support for a parallel port webcam,
as this is an obsolete technology;
3) the changes at gspca for it to work with parallel port would be very large;
4) this driver still uses BKL.

Add a new framework to handle controls which makes life for driver
developers much easier.
Note that this patch moves some of the control support that used to be in
v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body
of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function
in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl
struct anymore, which makes it more general.
The remainder of v4l2-ctrls.c is all new. Highlights include:
- No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL,
S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers
or subdevs. New wrapper functions are provided that can just be plugged in.
Once everything has been converted these wrapper functions can be removed as well.
- When subdevices are added their controls can be automatically merged
with the bridge driver's controls.
- Most drivers just need to implement s_ctrl to set the controls.
The framework handles the locking and tries to be as 'atomic' as possible.
- Ready for the subdev device nodes: the same mechanism applies to subdevs
and their device nodes as well. Sub-device drivers can make controls
local, preventing them from being merged with bridge drivers.
- Takes care of backwards compatibility handling of VIDIOC_S_CTRL and
VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent.
CTRL_CLASS controls are automatically added.

A mem-to-mem device is a device that uses memory buffers passed by
userspace applications for both their source and destination data. This
is different from existing drivers, which utilize memory buffers for either
input or output, but not both.
In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type.
Examples of such devices would be: image 'resizers', 'rotators',
'colorspace converters', etc.

Video subdevices, like cameras, decoders, connect to video bridges over
specialised busses. Data is being transferred over these busses in various
formats, which only loosely correspond to fourcc codes, describing how video
data is stored in RAM. This is not a one-to-one correspondence, therefore we
cannot use fourcc codes to configure subdevice output data formats. This patch
adds codes for several such on-the-bus formats and an API, similar to the
familiar .s_fmt(), .g_fmt(), .try_fmt(), .enum_fmt() API for configuring those
codes. After all users of the old API in struct v4l2_subdev_video_ops are
converted, it will be removed. Also add helper routines to support generic
pass-through mode for the soc-camera framework.

800x600, although the sensor supports 1600x1200. Sizes above 800x600 don't seem
to work correctly, besides, examples from the system integrator use sizes above
640x480 only for still photography. Unfortunately, I had to use "magic"
register-value pairs for undocumented and "reserved" registers. This version of
the driver also omits some functionality, like cropping, which hasn't been
sufficiently tested yet and will be added later.

Since i2c autoprobing is no longer supported by v4l2 we need to make sure
that the i2c modules are linked before the v4l2 modules. The v4l2 modules
now rely on the presence of the i2c modules, so these must have initialized
themselves before the v4l2 modules.
The exception is the ir-kbd-i2c module, which is the only one still using
autoprobing. This one should be loaded at the end of the v4l2 module. Loading
it earlier actually causes problems with tveeprom. Once ir-kbd-i2c is no
longer autoprobing, then it has to move up as well.
This is only an issue when everything is compiled into the kernel.
