Convert ov2640 to a standard subdev driver. The soc-camera driver no longer uses this driver, so it can safely be converted. Signed-off-by:

It is a bit confusing how CEC_CAP_RC and IS_REACHABLE(CONFIG_RC_CORE) interact. By stripping CEC_CAP_RC at the beginning rather than after #else it should be a bit clearer what is going on. Signed-off-by:

Currently when the RC Core is enabled (reachable) core code located in cec_register_adapter() attempts to populate the RC structure with a pointer to the 'parent' passed in by the caller. Unfortunately if the caller did not specify RC capability when calling cec_allocate_adapter(), then there will be no RC structure to populate. This causes a "NULL pointer dereference" error. Fixes: f51e8080 ("[media] cec: pass parent device in register(), not allocate()") Signed-off-by:

By using the CEC notifier framework there is no longer any reason to manually set the physical address. This was the one blocking issue that prevented this driver from going out of staging, so do this move as well. Update the bindings documenting the new hdmi phandle and update exynos4.dtsi accordingly. Tested with my Odroid U3. Signed-off-by:

Add support for CEC notifiers, which is used to convey CEC physical address information from video drivers to their CEC counterpart driver(s). Based on an earlier version from Russell King: https://patchwork.kernel.org/patch/9277043/ The cec_notifier is a reference counted object containing the CEC physical address state of a video device. When a new notifier is registered the current state will be reported to that notifier at registration time. Signed-off-by:

The DRM object does not register the pipe with the WPF object. This is used internally throughout the driver as a means of accessing the pipe. As such this breaks operations which require access to the pipe from WPF interrupts. Register the pipe inside the WPF object after it has been declared as the output.

With multiple inputs through the BRU it is feasible for the streams to race each other at stream-on. Multiple VIDIOC_STREAMON calls racing each other could have process N-1 skipping over the pipeline setup section and then start the pipeline early, if videobuf2 has already enqueued buffers to the driver for process N but not called the .start_streaming() operation yet In the case of the video pipelines, this can present two serious issues. 1) A null-dereference if the pipe->dl is committed at the same time as the vsp1_video_setup_pipeline() is processing 2) A hardware hang, where a display list is committed without having called vsp1_video_setup_pipeline() first Repair this issue, by ensuring that only the stream which configures the pipeline is able to start it.

The documentation for video capture and output devices claims that the video standard ioctls are required. This is not the case, they are only required for PAL/NTSC/SECAM type inputs and outputs. Sensors do not implement this at all and e.g. HDMI inputs implement the DV Timings ioctls. Just drop the mention of 'video standard' ioctls. Signed-off-by:
