2013-03-05[media] s2255: fix field handlingHans Verkuil
Just set the field value based on the chosen format. It's either INTERLACED or TOP. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] s2255: zero priv and set colorspaceHans Verkuil
Set priv field of struct v4l2_pix_format to 0 and fill in colorspace. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] s2255: fixes in the way standards are handledHans Verkuil
Instead of comparing against STD_NTSC and STD_PAL compare against 60 and 50 Hz formats. That's what you really want. When the standard is changed, make sure the width and height of the format are also updated to reflect the current standard. Also replace the deprecated current_norm by the g_std ioctl.

2013-03-05[media] gspca: Remove gspca-specific debug magicTheodore Kilgore
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 Nawrocki
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 Debski
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] stk-webcam: implement support for count == 0 when calling REQBUFSHans Verkuil
The spec specifies that setting count to 0 in v4l2_requestbuffers should result in releasing any streaming resources and the stream ownership. Implement this.

2013-03-05[media] stk-webcam: zero the priv field of v4l2_pix_formatHans Verkuil
The priv field should be set to 0. In this case the driver abused the priv field for internal housekeeping. Modify the code so priv is no longer used for that purpose.

2013-03-05[media] cx231xx: disable 417 support from the Conexant video grabberHans Verkuil
The 417 support doesn't work. Until someone can dig into this driver to figure out why it isn't working the 417 support is disabled. Sometimes you can actually stream a bit, but very soon the whole machine crashes, so something is seriously wrong. For the record, this was not introduced by my recent changes to this driver, it was broken before that.
