2013-03-05[media] stk-webcam: add support for control events and prio handlingHans Verkuil2-10/+18
Also correct the first_init static: this should be part of the stk_camera struct. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Tested-by: Arvydas Sidorenko <asido4@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] stk-webcam: don't use private_data, use video_drvdataHans Verkuil1-18/+14
file->private_data is needed to store the pointer to struct v4l2_fh. So use video_drvdata to get hold of the stk_camera struct. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Tested-by: Arvydas Sidorenko <asido4@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-03-05[media] cx231xx: disable 417 support from the Conexant video grabberHans Verkuil1-1/+4
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.

2013-03-05[media] cx231xx-417: fix g/try_fmt compliance problemsHans Verkuil1-15/+19
Colorspace, field and priv were not set, and sizeimage was calculated using the wrong values (dev->ts1.ts_packet_size and dev->ts1.ts_packet_count can be 0 at module load). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-03-05[media] cx231xx: improve std handlingHans Verkuil1-11/+13
Set the initial standard of subdevices instead of leaving it undefined. Also update the width and height when a new standard is chosen and return -EBUSY when attempting to change the standard while videobuf is busy.

2013-03-05[media] cx231xx: replace ioctl by unlocked_ioctlHans Verkuil2-10/+7
There was already a core lock, so why wasn't ioctl already replaced by unlock_ioctl? This patch switches to unlocked_ioctl. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] cx231xx: remove current_norm usageHans Verkuil2-3/+1
The use of this field is deprecated since it will not work when multiple device nodes reference the same video input (the video and vbi nodes in this case). The norm field should be a device-global value. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-03-05[media] cx231xx: zero priv field and use right width in try_fmtHans Verkuil1-1/+3
The priv field of v4l2_pix_format must be zeroed. Also fix a bug in try_fmt where the current width was used instead of the width passed to try_fmt. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] cx231xx: fix tuner compliance issuesHans Verkuil2-1/+5
The g_tuner call wasn't passed on to the subdevices, g_frequency didn't check for invalid tuners and a low-level function that was expected to return 0 or a negative error returned a positive number instead, causing s_frequency to return bogus errors.

2013-03-05[media] cx231xx: remove broken audio input support from the driverHans Verkuil1-44/+8
The audio selection code is broken. Audio and video indices were mixed up and s_audio would reject changing the audio input to something else anyway, so what's the point? All the audio input code has been removed. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] cx231xx: clean up radio supportHans Verkuil1-61/+18
Radio should not use video or audio inputs. In addition, fix a bug in radio_g_tuner where s_tuner was called in the tuner subdev instead of g_tuner. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

This driver now passes the tuner and frequency tests of v4l2-compliance. It's the usual bugs: frequency wasn't clamped to the valid frequency range, incorrect tuner capabilities and tuner fields not filled in, missing test for invalid tuner index, no initial frequency and incorrect error handling.
