* [media] soc_camera/mx3_camera.c: move to staging in preparation, for removalHans Verkuil2016-03-037-10/+21

| | | | | | | | | | | | | | | | | | The device initialization completes only after calling input_register_device(). However, rc_open() can be called while the device is being registered by the input/evdev core. So, we can't expect that rc_dev->initialized to be true. Change the logic to don't require initialized == true at rc_open and change the type of initialized to be atomic. this way, we can check for it earlier where it is really needed, without needing to lock the mutex just for testing it.

* | [media] bttv: Width must be a multiple of 16 when capturing planar formatsHans de Goede2016-03-011-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max size results in a solid green rectangle being captured (all colors 0 in YUV). This turns out to be caused by max-width (924) not being a multiple of 16. We've likely never hit this problem before since normally xawtv / tvtime, etc. will prefer packed pixel formats. But when using a video card which is using xf86-video-modesetting + glamor, only planar XVideo fmts are available, and xawtv will chose a matching capture format to avoid needing to do conversion, triggering the solid green window problem.

* | [media] media: au0828 handle media_init and media_register windowShuah Khan2016-02-271-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Media device initialization and registration steps are split. There is a window between media device init and media device register during usb probe. au0828 bridge driver and snd-usb-audio could try to initialize the media device, if they simply checked, whether the device has been registered. They also need to check whether the device has been initialized. Change the au0828-core to check if media device is already initialized during initialization step and check if media device is already registered during the registration step.

* | [media] media: au0828 change to use Managed Media Controller APIShuah Khan2016-02-271-7/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change au0828 to use Managed Media Controller API to share media device and coordinate creating/deleting the shared media device with the snd-usb-audio driver. The shared media device is created as device resource of the parent usb device of the two drivers. Populate media device model with USB Device product name instead of au0828 device board name. This change is necessary because, if the media device is registered by the snd-usb-audio driver first, and it doesn't know the au0828 board name.

* | [media] media: Change v4l-core to check if source is freeShuah Khan2016-02-273-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change s_input, s_fmt, s_tuner, s_frequency, querystd, s_hw_freq_seek, and vb2_core_streamon interfaces that alter the tuner configuration to check if it is free, by calling v4l_enable_media_source(). If source isn't free, return -EBUSY. v4l_disable_media_source() is called from v4l2_fh_exit() to release tuner (source). vb2_core_streamon() uses v4l_vb2q_enable_media_source().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new interfaces to be used by v4l-core to invoke enable source and disable_source handlers in the media_device. The enable_source helper function invokes the enable_source handler to find media source entity connected to the entity and check is it is available or busy. If source is available, link is activated and pipeline is started. The disable_source helper function invokes the disable_source handler to deactivate and stop the pipeline.
