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. Signed-off-by:

Add OKI Semiconductor ML86V7667 video decoder driver. [Sergei: added v4l2_device_unregister_subdev() call to the error cleanup path of ml86v7667_probe(), renamed ml86v7667_try_mbus_fmt() to ml86v7667_mbus_fmt(), killed v4l2_chip_match_i2c_client() checks in the [gs]_register() methods, fixed the prototype of the s_register() method, did some cleanup.] Signed-off-by:

get_video_info() should never return EFAULT, instead it should return the low-level usb_control_msg() error. Add a valid field to the hdpvr_video_info struct so the driver can easily check if a valid format was detected. Whenever get_video_info is called and it returns an error (e.g. usb_control_msg failed), then return that error to userspace as well. Signed-off-by:

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 After the FIMC-IS driver addition the assumptions made in the link_notify callback are no longer valid, e.g. the link between fimc-lite subdev and its video node is not immutable any more and there is more subdevs than just sensor, MIPI-CSIS and FIMC(-LITE).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). Signed-off-by:

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.

Protect the fimc/fimc-lite video nodes unregistration with their video lock. This prevents a kernel crash when e.g. udev opens a video node right after the driver registers it and then the driver tries to unregister it and defers its probing. Using video_is_unregistered() together with the video mutex allows safe unregistration of the video nodes at any time. Signed-off-by:

Remove driver private video node reference counters and use entity->use_count instead. This makes the video pipelines power handling more similar to the method used in omap3isp driver. Now the graph mutex is taken always after the video mutex, as it is not possible to ensure apposite order at the all modules. Signed-off-by:

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. Signed-off-by:
