The em28xx driver has changed much, especially since kernel 3.8. So it's time to bump the driver version. Changes since kernel 3.8: - converted the driver to videobuf2 - converted the driver to the v4l2-ctrl framework - added USB bulk transfer support - use USB bulk transfers by default for webcams (allows streaming from multiple devices at the same time) - added image quality bridge controls: contrast, brightness, saturation, blue balance, red balance, sharpness - removed dependency from module ir-kbd-i2c - cleaned up the frame data processing code - removed some unused/obsolete code - made remote controls of devices with external (i2c) receiver/decoder work again - fixed audio over USB for device "Terratec Cinergy 250" - several v4l2 compliance fixes and improvements (including fixes for ioctls enabling/disabling) - lots of further bug fixes and code improvements Signed-off-by:

Add the image quality bridge controls contrast, brightness, saturation, blue balance, red balance and sharpness. These controls are enabled only if no subdevice provides them. Tested with the following devices: "Terratec Cinergy 200 USB" "Hauppauge HVR-900" "SilverCrest 1.3MPix webcam" "Hauppauge WinTV USB2" "Speedlink VAD Laplace webcam" Signed-off-by:

The image quality default values will be used in at least two different places and by using #defines we make sure that they are always consistent. Signed-off-by:

The maximum supported scaling value for registers 0x30+0x31 (horizontal scaling) and 0x32+0x33 (vertical scaling) is 0x3fff, which corresponds to 20% of the input frame size. Signed-off-by:

vidioc_s_fmt_vbi_cap() is a 100% duplicate of vidioc_g_fmt_vbi_cap() and therefore can be removed. Signed-off-by:

Frank Schaefer authored
The em28xx driver doesn't support the VIDIOC_G_CROP and VIDIOC_S_CROP ioctls, so VIDIOC_CROPCAP is useless and has the potential to confuse applications, because it can be interpreted as indicator for cropping support. Signed-off-by:

Pull fbdev UAPI disintegration from David Howells: "You'll be glad to here that the end is nigh for the UAPI patches. Only the fbdev/framebuffer piece remains now that the SCSI stuff has gone in. Here are the UAPI disintegration bits for the fbdev drivers. It appears that Florian hasn't had time to deal with my patch, but back in December he did say he didn't mind if I pushed it forward." Yay. No more uapi movement. And hopefully no more big header file cleanups coming up either, it just tends to be very painful. * tag 'disintegrate-fbdev-20121220' of git://git.infradead.org/users/dhowells/linux-headers: UAPI: (Scripted) Disintegrate include/video
