2013-03-05[media] cx231xx-417: remove empty functionsHans Verkuil1-67/+1
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. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] cx231xx: get rid of a bunch of unused cx231xx_fh fieldsHans Verkuil2-22/+2

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: add struct v4l2_fh to get prio and event supportHans Verkuil2-5/+28
Required to resolve v4l2-compliance failures. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] cx231xx: convert to the control frameworkHans Verkuil4-236/+27
This is needed to resolve the v4l2-compliance complaints about the control ioctls. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] cx231xx: fix vbi compliance issuesHans Verkuil1-50/+17
Various v4l2-compliance fixes: remove unused sliced VBI functions, zero the reserved fields of struct v4l2_vbi_format and implement the missing s_fmt_vbi_cap. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] cx231xx: fix frequency clampingHans Verkuil1-9/+2
Let the tuner clamp the frequency and store that clamped value. This fixes a v4l2_compliance failure. 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. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
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>
2013-03-05[media] cx231xx: add required VIDIOC_DBG_G_CHIP_IDENT supportHans Verkuil1-0/+14

2013-03-05[media] cx231xx: add device_caps support to QUERYCAPHans Verkuil1-6/+10
This fixes a v4l2_compliance failure. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
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. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
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>
2013-03-05[media] bttv: fix try_fmt_vid_overlay and setup initial overlay sizeHans Verkuil1-19/+25
try_fmt_vid_overlay should map incorrect sizes and fields to valid values. It also expects that an initial overlay size is defined so g_fmt_vid_overlay returns valid information. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] bttv: fix g_tuner capabilities overrideHans Verkuil2-2/+2
The capability field of v4l2_tuner should be ORed by the various subdevs and by the main driver. In this case the stereo capability was dropped. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] bttv: there may be multiple tvaudio/tda7432 devicesHans Verkuil1-4/+10
Probe for additional tvaudio devices, and allow tvaudio+tda7432 to co-exist. My STB TV PCI FM bttv card has a tda7432, a tda9850 and a tea6420 and with this patch it finally works again (probably for the first time in many years).

2013-03-05[media] bttv: use centralized std and implement g_stdHans Verkuil2-1/+13
The 'current_norm' field cannot be used if multiple device nodes (video and vbi in this case) set the same std. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] bttv: fix priority handlingHans Verkuil2-61/+6

2013-03-05[media] bttv: convert to the control frameworkHans Verkuil3-437/+266
Note that the private chroma agc control has been replaced with the standard CHROMA_AGC control. Also fixes a mute/automute problem where closing the file handle would force mute on. That's not what you want since that would make the mute state out of sync with the mute control. Instead check against the user count.

2013-03-05[media] bttv: fix field handling inside TRY_FMTHans Verkuil1-16/+12
- don't return -EINVAL for invalid field types, handle those as if it was FIELD_ANY. - the handling of FIELD_SEQ_BT/TB was wrong as well: if such field formats aren't supported, then fall back to FIELD_ANY instead of returning an error.

2013-03-05[media] bttv: set initial tv/radio frequenciesHans Verkuil2-7/+30
Set an initial frequencies when the driver is loaded. That way G_FREQUENCY will give a frequency that corresponds with reality. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] bttv: disable g/s_tuner and g/s_freq when no tuner present, fix ↵Hans Verkuil1-28/+16
return codes If no tuner is present, then disable the tuner and frequency ioctls. We can remove a number of checks from those ioctls testing for the presence of a tuner. Also remove some tuner type checks (now done by the core) and fix an error return when the prio check fails. Finally some 'unlikely' statements are removed since those only make sense in tightly often executed loops, otherwise they just clutter up the code.

2013-03-05[media] bttv: fix querycap and radio v4l2-compliance issuesHans Verkuil1-74/+27
The querycap ioctl didn't support V4L2_CAP_DEVICE_CAPS and the radio device implemented audio and video inputs and s_std, which are not part of the radio API. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
