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 RPF and WPF U/V order bits have no effect for 3-planar formats on Gen3 hardware. Swap the U and V planes addresses manually instead in that case. Fixes: b915bd24 ("[media] v4l: vsp1: Add tri-planar memory formats support") Signed-off-by:

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:

Most ioctls do not have to write back the contents of the argument if an error is returned. But VIDIOC_S_EDID is an exception together with the EXT_CTRLS ioctls (already handled correctly). Add this exception to v4l2-compat-ioctl32. This fixes a compliance error when using compat32 and trying to set a new EDID with more blocks than the hardware supports. In that case the driver will return -E2BIG and set edid.blocks to the actual maximum number of blocks. This field was never copied back to userspace due to this bug. Signed-off-by:
