2013-04-16[media] cx25821: replace custom ioctls with write()Hans Verkuil
Ideally this should be implemented with vb2, but it'll do for now. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: drop cx25821-video-upstream-ch2.c/hHans Verkuil
cx25821-video-upstream_ch2.c/h is practically identical to cx25821-video-upstream.c/h so add support for ch2 into cx25821-video-upstream.c instead. After this we can replace the custom ioctls with a proper write() interface. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-04-16[media] cx25821: group all fmt functions togetherHans Verkuil
No other changes, just function reordering. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: setup output nodes correctlyHans Verkuil
Drop the custom ioctls and enable the video output nodes again, this time using standard ioctls. The next step will be to provide a proper write() interface. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: remove references to subdevices that aren't thereHans Verkuil
This driver does not have subdevices, so why call subdev ops? After removing that it became apparent that only Composite is supported as input, so remove also any reference to other inputs.

2013-04-16[media] cx25821: remove custom ioctls that duplicate v4l2 ioctlsHans Verkuil
No idea why these custom ioctls exist: they have perfectly normal v4l2 counterparts which are already implemented. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: g/s/try/enum_fmt related fixes and cleanupsHans Verkuil
- fill in colorspace - zero priv - delete unsupported formats - fix field handling - s_std should update width/height - proper mapping of width/height to valid resolutions Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: switch to v4l2_fh, add event and prio handlingHans Verkuil
It is now possible to remove cx25821_fh and replace it with v4l2_fh, which in turn makes event handling and core prio handling possible. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: replace resource management functions with fh ownershipHans Verkuil
Just remember which filehandle is streaming instead of using complicated resource masks. After this patch we can replace cx25821_fh with v4l2_fh. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: move vidq from cx25821_fh to cx25821_channelHans Verkuil
This is not a per-filehandle object, it's a per-channel object. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: remove 'type' field from cx25821_fhHans Verkuil

2013-04-16[media] cx25821: remove unnecessary debug messagesHans Verkuil
The v4l2 core already has support for debugging ioctls/file operations. No need to do that again. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-04-16[media] cx25821: embed video_device, clean up some kernel log spamHans Verkuil
Embed the video_device struct instead of allocating it. Remove some of the annoying and ugly kernel messages shown during loading and unloading of the module. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: remove bogus dependenciesHans Verkuil

2013-04-16[media] cx25821: remove cropping ioctlsHans Verkuil

2013-04-16[media] cx25821: make lots of externals staticHans Verkuil

2013-04-16[media] cx25821: s_input didn't check for invalid inputHans Verkuil
The s_input implementation allowed input 1 even if that didn't exist. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: remove unnecessary global devlistHans Verkuil
This device list is not necessary. The kernel already has all that information, so just use that instead. Also remove a bogus refcount and some dead 'private_free' code in the alsa driver. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: make cx25821_sram_channels constHans Verkuil

2013-04-16[media] cx25821: fix log_status, querycapHans Verkuil
log_status shouldn't print LOG STATUS lines, the core does that already. Fix querycap version number and add device_caps support. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: remove unused fields, ioctlsHans Verkuil
Do some spring cleaning: - there are no board defines with tuners, so remove bogus tuner support. - tv standard handling has nothing to do with tuners, so keep that. - replace the deprecated current_norm by g_std. - querystd isn't implemented, so remove the ioctl. - remove a bunch of unused fields in cx25821.h Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-16[media] cx25821: remove bogus radio/vbi/'video-ioctl' supportHans Verkuil
This device does not support radio or vbi, so remove anything referring to that. In addition, the driver created an 'video ioctl' node, which was unused and was effectively identical to the first video node. This bogus video node is now removed, leaving us with 8 video capture nodes and 2 video output nodes.

2013-04-15[media] cx25821: the audio channel was registered as a video nodeHans Verkuil
Skip the audio channel when registering the video nodes. This fixes a bug where that incorrectly registered 'video' node was never unregistered. Note: this bug only surfaces if the video output nodes are enabled again after the previous patch disabled them. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-15[media] cx25821: do not expose broken video output streamsHans Verkuil
The cx25821 driver has support for one audio output channel and two video output channels. This is implemented in a very ugly and very evil way through a custom ioctl that passes the filename of a file containing the video data, which is then read by the driver itself using vfs. There are a number of problems with this: 1) it's very ugly and very evil (I can't say that often enough). 2) V4L2 supports video output, so why not use that? 3) it's very buggy, closing the filehandle through which you passed the ioctl will oops the kernel. 4) it's a nasty security leak since this allows you to load any file in the system as a video or audio source, so in theory you can output /etc/passwd to audio or video out and record & decode it on another device. Because of all these issues we no longer register those output video nodes. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-04-14[media] soc-camera: fix typos in the default format-conversion tableGuennadi Liakhovetski
The default format conversion table mbus_fmt[] in soc_mediabus.c lists "natural" conversions between media-bus and fourcc pixel formats, that are achieved by storing data from the bus in RAM exactly as it arrives, only possibly padding missing high or low bits. Such data acquisition mode cannot change data endianness, therefore two locations with opposite endianness are erroneous. This change might affest the omap1-camera driver, existing configurations should be verified.
