* [media] v4l: v4l2_subdev userspace format APILaurent Pinchart2011-03-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

* [media] v4l2-subdev: add (un)register internal opsHans Verkuil2011-01-191-0/+17
| | | | | | | | | | | | | | | | | | | Some subdevs need to call into the board code after they are registered and have a valid struct v4l2_device pointer. The s_config op was abused for this, but now that it is removed we need a cleaner way of solving this. So this patch adds a struct with internal ops that the v4l2 core can call. Currently only two ops exist: register and unregister. Subdevs can implement these to call the board code and pass it the v4l2_device pointer, which the board code can then use to get access to the struct that embeds the v4l2_device. It is expected that in the future open and close ops will also be added.

* V4L/DVB: v4l2: Add new control handling frameworkHans Verkuil2010-08-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new framework to handle controls which makes life for driver developers much easier. Note that this patch moves some of the control support that used to be in v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl struct anymore, which makes it more general. The remainder of v4l2-ctrls.c is all new. Highlights include: - No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL, S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers or subdevs. New wrapper functions are provided that can just be plugged in. Once everything has been converted these wrapper functions can be removed as well. - When subdevices are added their controls can be automatically merged with the bridge driver's controls. - Most drivers just need to implement s_ctrl to set the controls. The framework handles the locking and tries to be as 'atomic' as possible. - Ready for the subdev device nodes: the same mechanism applies to subdevs and their device nodes as well. Sub-device drivers can make controls local, preventing them from being merged with bridge drivers. - Takes care of backwards compatibility handling of VIDIOC_S_CTRL and VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent. CTRL_CLASS controls are automatically added.

* V4L/DVB: cx25840, v4l2-subdev, ivtv, pvrusb2: Fix ivtv/cx25840 tinny audioAndy Walls2010-02-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change attempts to fix the ivtv tinny audio problem by keeping digitizer to encoder audio clocks running, while disabling the video clocks as needed to avoid unpredictable PCI bus hangs. To accomplish this, for the cx25840 module enabling of audio streaming had to be separated from enabling video streaming, requiring an additional v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers. The cx231xx and cx23885 driver use the cx25840 module for affecting only video on s_stream calls, so those drivers needed no change. The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI bus hang, so the cx18 driver did not need corresponding changes. CX2341[56] based cards that are not using the CX2584x family of chips do not seem to be affected by the tinny audio problem, and this change should not affect how they are configured. It will delay their first capture by starting by another 300 msec though. Many thanks go to Argus <pthorn-ivtvd@styx2002.no-ip.org> and Martin Dauskardt <martin.dauskardt@gmx.de> whose persistent testing and investigation of this problem will hopefully fix this problem once and for all for many ivtv users.

* V4L/DVB (13658): v4l: add a media-bus API for configuring v4l2 subdev pixel ↵Guennadi Liakhovetski2009-12-161-1/+17
| | | | | | | | | | | | | | | | | | | | | | | and frame formats Video subdevices, like cameras, decoders, connect to video bridges over specialised busses. Data is being transferred over these busses in various formats, which only loosely correspond to fourcc codes, describing how video data is stored in RAM. This is not a one-to-one correspondence, therefore we cannot use fourcc codes to configure subdevice output data formats. This patch adds codes for several such on-the-bus formats and an API, similar to the familiar .s_fmt(), .g_fmt(), .try_fmt(), .enum_fmt() API for configuring those codes. After all users of the old API in struct v4l2_subdev_video_ops are converted, it will be removed.

* V4L/DVB (12125): v4l2: add new s_config subdev ops and ↵Hans Verkuil2009-06-231-1/+6
| | | | | | | | | | | | | | | | | | | | v4l2_i2c_new_subdev_cfg/board calls Add a new s_config core ops call: this is called with the irq and platform data to be used to initialize the subdev. Added new v4l2_i2c_new_subdev_cfg and v4l2_i2c_new_subdev_board calls that allows you to pass these new arguments. The existing v4l2_i2c_new_subdev functions were modified to also call s_config. In the future the existing v4l2_i2c_new_subdev functions will be replaced by a single v4l2_i2c_new_subdev function similar to v4l2_i2c_new_subdev_cfg but without the irq and platform_data arguments.

| | | | | | | | | | | | | v4l2_device. Until now I relied on i2c_del_adapter to unregister the i2c_clients for me, however, if the i2c bus is a platform bus then it is never deleted. So instead I need to unregister i2c clients when unregistering the v4l2_device. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | It is no longer needed to use a struct pointer as argument, since v4l2_subdev doesn't require that ioctl-like approach anymore. Instead just pass the input, output and config (new!) arguments directly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | v4l2_subdev. With all the v4l2_subdev changes that were made to these drivers it is a good idea to increase the version number of each driver. It's just the patch level that is increased, except for the zoran and saa7146 drivers where the minor number was increased due to the more substantial changes that were made to those two drivers.

* V4L/DVB (11370): v4l2-subdev: move s_std from tuner to core.Hans Verkuil2009-04-061-1/+1
| | | | | | | | | s_std didn't belong in the tuner ops. Stricly speaking it should be part of the video ops, but it is used by audio and tuner devices as well, so it is more efficient to make it part of the core ops.
