- The video device is not allocated when mt9t031_init() is called, don't use
it in debug printk.

- The clock polarity is inverted in mt9t031_set_bus_param(), use the correct
one.

d75b1dcc84 V4L/DVB (11031): pcm990 baseboard: add camera bus width switch setting
Some Phytec cameras have a I2C GPIO expander which allows it to
switch between different sensor bus widths. This was previously
handled in the camera driver. Since handling of this switch
varies on several boards the cameras are used on, the board
support seems a better place to handle the switch

28f59339f7 V4L/DVB (11030): soc-camera: add board hook to specify the buswidth for camera sensors
Camera sensors have a native bus width say support, but on some
boards not all sensor data lines are connected to the image
interface and thus support a different bus width than the sensors
native one. Some boards even have a bus driver which dynamically
switches between different bus widths with a GPIO.

This patch adds a hook which board code can use to support different
bus widths.

025c18a19d V4L/DVB (11027): soc-camera: configure drivers with a default format at probe time
Currently soc-camera doesn't set up any image format without an explicit
S_FMT. According to the API this should be supported, for example,
capture-example.c from v4l2-apps by default doesn't issue an S_FMT. This
patch moves negotiating of available host-camera format translations to
probe() time, and restores the state from the last close() on the next
open(). This is needed for some drivers, which power down or reset
hardware after the last user closes the interface. This patch also has a
nice side-effect of avoiding multiple allocation anf freeing of format
translation tables.

005759613b V4L/DVB (10988): v4l2-dev: use parent field if the v4l2_device has no parent set.
Normally the parent device of v4l2_device is used as the video device
node's parent. But if it was not set, then use the parent field in the
video_device struct.

This is needed in the cx88 driver, which has one core v4l2_device but
creates multiple pci devices (one each for raw and mpeg video).

So you cannot associate the core v4l2_device with a particular PCI device,
but you can do that for each video_device.

The frame headers contain information which may be useful in processing
