Let the po1030 have a local v4l2 ctrl cache as this minimizes the load on reading the registers and improves performance.

s5k83a sensor mounted on many acer laptops have a swiwel allowing it to be rotated. When the camera is in its rotated state, the image needs to be flipped. The only way to check for if the camera has been flipped is to continously poll a register in the m5602. This patch creates a kernel thread which does this. This patch renames some v4l2 ctrls and finally implements a cache in order to prevent unnecessary sensor reads.

Touching the hflip/vflip register while doing the read/modify/write corrupts the image. Just read from the sensor ctrl cache instead and all is good.

The vflip quirk is better checked at probe time as it's only needed once.
Also add an extra reset at init time to resolve a suspend to ram regression.

Reading and writing to a register doesn't always work reliably. Add a cache
and ensure that it is deallocated properly upon module disconnect.

Previously all resolution setting was done with precalculated tables.
When the image is vflipped we need to adjust the alignment which would
require another table. Now we can adjust the parameters on the fly instead.

ov9650: Reading the COM1 register corrupts the image.
Decrease the granularity of the exposure and limit its upper range
as setting such high values doesn't have any effect on the image.

Add support to the SQ-905 driver to pass back to user space the
sensor orientation information obtained from the camera during init.
Modifies gspca and the videodev2.h header to create the necessary

The v4l2-ioctl core checks the buffer type now by only allowing buffer
types for which the corresponding ->vidioc_try_fmt_xxx() methods are
defined.
This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE
buffers are allowed to be used with vidioc_g_parm. Also,
->vidioc_enum_fmt_vid_cap() is only called for VIDEO_CAPTURE buffers.
There is no need to set the buffer type since it must already be the
correct value.
The struct which ->vidioc_querycap() is supposed to fill in is already
zeroed so it's not necessary to call memset on it.

Prefer the gspca sonixj driver for the Philips SPC600NC webcam instead of
the sn9c102 driver. As we've got userreports that it works with the gspca
driver, whereas it fails with the sn9c102 driver, see:

the same set of cameras in stillcam mode. I am a co-author of gspca/sq905.c and
