* [media] exynos4-is: Extend link_notify handler to support fimc-is/lite pipelinesSylwester Nawrocki2013-06-121-22/+81
| | | | | | | | | | | | | | | | This patch corrects the link_notify handler to support more complex pipelines, including fimc-lite and fimc-is entities. After the FIMC-IS driver addition the assumptions made in the link_notify callback are no longer valid, e.g. the link between fimc-lite subdev and its video node is not immutable any more and there is more subdevs than just sensor, MIPI-CSIS and FIMC(-LITE). The graph is now walked and for each video node found a media pipeline which ends at this node is disabled/enabled (the subdevs are powered on/off).

* [media] media: Change media device link_notify behaviourSylwester Nawrocki2013-06-123-37/+40
| | | | | | | | | | | | | | | | | | | | | | | | Currently the media device link_notify callback is invoked before the actual change of state of a link when the link is being enabled, and after the actual change of state when the link is being disabled. This doesn't allow a media device driver to perform any operations on a full graph before a link is disabled, as well as performing any tasks on a modified graph right after a link's state is changed. This patch modifies signature of the link_notify callback. This callback is now called always before and after a link's state change. To distinguish the notifications a 'notification' argument is added to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates notification before link's state change and MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after link flags change.

* [media] exynos4-is: Preserve state of controls between /dev/video open/closeSylwester Nawrocki2013-06-123-53/+50
| | | | | | | | | | | | | | | | | | | | | | This patch moves the code for inheriting subdev v4l2 controls on the FIMC video capture nodes from open()/close() fops to the link setup notification callback. This allows for the state of the FIMC controls to be always kept, in opposite to the current situation when it is lost when last process closes video device. There is no visible change for the original V4L2 compliant interface. For the MC aware applications (user_subdev_api == true) inheriting of the controls is dropped, since there can be same controls on the subdevs withing single pipeline, now when the ISP (FIMC-IS) is also used. This patch is a prerequisite to allow /dev/video device to be opened without errors even if there is no media links connecting it to an image source (sensor) subdev. This is required for a libv4l2 plugin to be initialized while a video node is opened and it also should be possible to always open the device to query the capabilities.
