2013-03-05[media] gspca: Remove gspca-specific debug magicTheodore Kilgore44-403/+373
Instead use v4l2_dbg and v4l2_err. Note that the PDEBUG macro is kept to make this patch-set less invasive, but it is simply a wrapper around v4l2_dbg now. Most of the other changes are there to make the dev parameter for the v4l2_xxx macros available everywhere we do logging.

2013-03-05[media] s3c-camif: Fail on insufficient number of allocated buffersSylwester Nawrocki1-4/+11
Ensure the driver gets always at least its minimum required number of buffers allocated by checking actual number of allocated buffers in vb2_reqbufs(). And free any partially allocated buffer queue with signaling an error to user space. Without this patch applications may wait forever to dequeue a filled buffer, because the hardware didn't even start after VIDIOC_STREAMON, VIDIOC_QBUF calls, due to insufficient number of empty buffers.

2013-03-05[media] vb2: Add support for non monotonic timestampsKamil Debski17-2/+23
Not all drivers use monotonic timestamps. This patch adds a way to set the timestamp type per every queue. In addition, set proper timestamp type in drivers that I am sure that use either MONOTONIC or COPY timestamps. Other drivers will correctly report UNKNOWN timestamp type instead of assuming that all drivers use monotonic timestamps.

2013-03-05[media] bttv: remove g/s_audio since there is only one audio inputHans Verkuil1-19/+0
Note that the current driver does not implement enumaudio (so apps cannot tell that audio inputs are present), it does not set V4L2_CAP_AUDIO, nor does it set audioset when calling ENUM_INPUT. And G_AUDIO doesn't set the stereo flag either. So these g/s_audio ioctls are quite pointless and misleading. Especially since some surveillance boards do not have audio at all.

2013-03-05[media] bttv: do not switch to the radio tuner unless it is accessedHans Verkuil2-3/+21
Just opening the radio tuner should not cause a switch to the radio tuner. Only after calling g/s_tuner or g/s_frequency should this happen. This prevents audio being unmuted as soon as the driver is loaded because some process opens /dev/radioX just to see what sort of node it is, which switches on the radio tuner and unmutes audio. This code can be improved further by actually keeping track of who owns the tuner and returning -EBUSY if switching tuner modes will cause problems. But for now just fix the annoying case where on boot the radio turns on automatically. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
