Subject: gspca_pac207: enable higher framerates / lower exposure settings

From: Hans de Goede <hdegoede@redhat.com>

Now that we've figured out the higher compression settings (supported in
libv4l-0.6.0 and later, so after this patch the driver should be used with
libv4l-0.6.0 or higher only!), we can enable higher framerates. Which
means lower exposure times, which is important for the use of the pac207
in full daylight.

This patch also tweakes the brightness default and the per color gain
balances to use the values which are adviced by Pixart in the pac207
application note.

Subject: gspca: mr97310a add support for CIF and more VGA camera's

From: Theodore Kilgore <kilgota@auburn.edu>

This patch adds supports for mr97310a camera's with CIF sensors (2 different
types) and for VGA mr97310a camera with a different sensor then supported
until now.

This patch also add support for controls for one of the 2 CIF sensors, this
was written by Thomas Kaiser <thomas@kaiser-linux.li>

gspca_mr97310a: Move detection of CIF sensor type to probe() function,
so that the right controls are set to disabled from the start, rather then
having them disappear all of a sudden when the stream is started.
