Adds a code that (auto)detects gm7113c clones. The auto-detection
here is not perfect, as, on contrary to what it would be expected
by looking into its datasheets some devices would return, instead:

ov7675 and ov7670 share the same registers but there is no way
to distinguish them at runtime. However, they require different
tweaks to achieve the desired resolution. For this reason this
patch adds a new ov7675 entry to the ov7670_id table.

All drivers which use this subdevice use also the control framework.
The v4l2_subdev_core_ops operations {query/g_/s_}ctrl are useless because
device drivers will inherit controls from this subdevice.

The current code was implemented with some default configurations,
this default configuration works on board and doesn't work on other.
This patch accepts the configuration through platform data and configures

Add driver for S5C73M3 image sensor. The driver exposes the sensor as
two subdevs: pure sensor and output interface. Two subdev architecture
supports interleaved UYVY/JPEG image format with separate frame size
for both sub-formats, there is a spearate pad for each sub-format.

This patch adds V4L2 sub-device driver for OV9650/OV9652 image sensors.
The driver exposes following V4L2 controls:
- auto/manual exposure,
- auto/manual white balance,
- auto/manual gain,
- brightness, saturation, sharpness,
- horizontal/vertical flip,
- color bar test pattern,
- banding filter (power line frequency).
Frame rate can be configured with g/s_frame_interval pad level ops.
Supported resolution are only: SXGA, VGA, QVGA.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

This kind of memcpy() is error-prone. Its replacement with a struct
assignment is prefered because it's type-safe and much easier to read.
Found by coccinelle. Hand patched and reviewed.
Tested by compilation only.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

struct struct_name from;

4x gain ceiling is not enough to capture a decent image in conditions
of total darkness and only a LED light source. Allow a maximum gain
of 32x instead.
This doesn't have any drawback since the image quality in 'normal'

Some camera systems cannot operate mt9v022 in normal mode and use
only the snapshot mode. The TechNote for mt9v022 (TN0960) and mt9v024
(TN-09-225) describes required register settings when configuring the
snapshot operation. The snapshot mode requires that certain automatic
functions of the image sensor should be disabled or set to fixed values.
According to the TechNote bit 2 and bit 9 in the register 0x20 must be
set in snapshot mode and unset for normal operation. This applies for
mt9v022 Rev.3 and mt9v024. Add required reg. 0x20 settings dependent on
sensor chip version.
