      [media] via-camera: specify XO-1.5 camera clock speed · a39fbb1d
      Daniel Drake authored
      For the ov7670 camera to return images at the requested frame rate,
      it needs to make calculations based on the clock speed, which is
      a completely external factor (depends on the wiring of the system).
      
      On the XO-1.5, which is the only known via-camera user, the camera
      is clocked at 90MHz.
      
      Pass this information to the ov7670 driver, to fix an issue where
      a framerate of 3x the requested amount was being provided.

      [media] v4l2-dev.h: add comment not to use V4L2_FL_LOCK_ALL_FOPS in new drivers · 47bd4bc1
      Hans Verkuil authored
      This flag is for legacy drivers only and will go away in the future.
      
      A note regarding commit 5126f259
      (v4l2-dev: add flag to have the core lock all file operations):
      
      That commit message suggests that by not taking the core lock for fops
      other than unlocked_ioctl all problems relating to AB-BA locking and
      mm->mmap_sem are solved. This is not the case.
      
      More work needs to be done by moving the core lock further down into
      video_ioctl2. It should only be taken after the copy_from/to_user calls
      are done.

      Besides the usual inconsistencies in input enumeration there was also a

      The B&W control never worked, and you get the same effect by setting saturation to the

      [media] saa7146: fix querycap, vbi/video separation and g/s_register · ab49ae0f
      Hans Verkuil authored
      The querycap ioctl returned an incorrect version number and incorrect
      capabilities (mixing up vbi and video caps).
      
      The reason for that was that video nodes could do vbi activities: that
      should be separated between the vbi and video nodes.
      
      There were also a few minor problems with dbg_g/s_register that have
      been resolved. The mxb/saa7146 driver now passes the v4l2_compliance tests.

      Instead of using custom ioctls use the VIDIOC_ENUM/G/S/_AUDIO ioctls.
      Also send the same audio to both CDROM-out and line-out.
      
      This is what you would expect and anyway, the CDROM-out connector is unlikely
      to be used these days as it is obsolete.

      to select the light metering mode for automatic exposure as one
      of the following modes: spot (small area at the frame center),
      center weighted and frame averaged.
