V4L/DVB (12618): gspca: mr97310a add support for CIF and more VGA camera's
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> Signed-off-by: Theodore Kilgore <kilgota@auburn.edu> Signed-off-by: Thomas Kaiser <thomas@kaiser-linux.li> Signed-off-by: Hans de Goede <hdgoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
