The framework documentation used the g_chip_ident op as an example. This op has been removed, so replace its use in the examples by the g_std op.

Replace the V4L2_IDENT_* usage with tveeprom-specific defines. This header is deprecated, so those defines shouldn't be used anymore.

Drop support for V4L2_CHIP_MATCH_I2C_DRIVER/ADDR and V4L2_CHIP_MATCH_AC97 types. The following patches will remove support for those in the drivers as well. This means that bridge drivers no longer have to check for the match.type field in their g/s_register implementations. Only if they also implement g_chip_info do they still have to check the match.addr field, otherwise the core will check for that as well.

Remove init_enable from ths7303 pdata as it is being dropped from ths7303_platform_data. The purpose of init_enable was that the device should start streaming video immediately but instead the bridge drivers should call s_stream explicitly for such devices. This is in fact what happens for the dm365, so setting init_enable here never made sense in the first place.

2013-06-13[media] exynos4-is: Extend link_notify handler to support fimc-is/lite pipelinesSylwester Nawrocki1-22/+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 After the FIMC-IS driver addition the assumptions made in the link_notify callback are no longer valid, e.g. the link between fimc-lite subdev and its video node is not immutable any more and there is more subdevs than just sensor, MIPI-CSIS and FIMC(-LITE).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).

2013-06-13[media] media: Change media device link_notify behaviourSylwester Nawrocki4-39/+47
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.
