81f2030a93 [media] video/Kconfig: Fix mis-classified devices
The helper chips are classified by their function. Unfortunaltely,
with time, developers added their stuff into the wrong places.

Fix it by moving itens to be at the right place. Also add a new
category for sensors and for misc devices that are found only on
a certain specific board.

While here, fix two bad whitespaces at Kconfig.

e23ccc0ad9 [media] v4l: add videobuf2 Video for Linux 2 driver framework
Videobuf2 is a Video for Linux 2 API-compatible driver framework for
multimedia devices. It acts as an intermediate layer between userspace
applications and device drivers. It also provides low-level, modular
memory management functions for drivers.

Videobuf2 eases driver development, reduces drivers' code size and aids in
proper and consistent implementation of V4L2 API in drivers.

Videobuf2 memory management backend is fully modular. This allows custom
memory management routines for devices and platforms with non-standard
memory management requirements to be plugged in, without changing the
high-level buffer management functions and API.

The framework provides:
- implementations of streaming I/O V4L2 ioctls and file operations
- high-level video buffer, video queue and state management functions
- video buffer memory allocation and management

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

f037484337 [media] tda9875: remove duplicate driver
In commit 411674fd18 the tda9875 support was
added to tvaudio. This means that tda9875 is no longer used since mid-2009.

If there are out-of-tree users of this driver, then they can switch to tvaudio
instead.

The original commit message read as follows:

    This change allows bttv to use tvaudio for this device. Since this device
    has the same i2c address as the tda9874 we need to support both in the same
    tvaudio driver. This makes it possible for tvaudio to detect which chip is
    used. Originally the tda9875 was only available in the dedicated tda9875
    driver, but that makes life very hard for bttv since loading tvaudio might
    misdetect a tda9875 as a tda9874.

So there were good reasons for moving the tda9875 code into tvaudio.

The only remaining drivers to depend on VIDEO_IR are bt8xx and

Rename VIDEO_IR -> IR_LEGACY to give a hint to anyone writing or

67826235ee [media] V4L: add an IMX074 sensor soc-camera / v4l2-subdev driver
This patch adds an initial driver for the IMXъ74 image sensor from Sony.
Lacking documentation, only very basic functionality in one specific image
format has been implemented and tested.

2f6e240479 [media] SoC Camera: add driver for OV6650 sensor
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.

bdc621fced [media] SoC Camera: add driver for OMAP1 camera interface
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.

Created and tested against linux-2.6.36-rc5 on Amstrad Delta.

96322b80e2 V4L/DVB: Deprecate stradis driver
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.

7af97effb3 V4L/DVB: Deprecate cpia driver (used for parallel port webcams)
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.

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.
