This capture device only supports 'V4L2_CAP_VIDEO_CAPTURE', so only need '*num_planes = 1'.
And, if you return here
The reason for doing this is to pass the test of 'v4l2-compliance 1.29.0-5246'.
+ } else {You can skip the else {}+ *num_planes = 1; + sizes[0] = pix->sizeimage;And here set the number of planes to the correct number and set the size of each plane ?
The reason for doing this is to pass the test of 'v4l2-compliance 1.29.0-5246'.
And now I realized you're using the single-planar API for buffer
management
vb2_q->type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
I was expecting it to rather be
vb2_q->type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
Even more so as you support multiplanar YUV formats.
Any reason why you chose to use the single planar API ?
I think the single-planar API is a bit simpler. Will try to use multi-planar.

FRAME_SYNC should ideally be emitted as soon as the processing of a frame start. Do you have other interrupt sources you can use to detect "start processing of a frame" ?
Will check the C308L datasheet.

+ + return media_device_register(&isp->media_dev);Any reason you're registering the media device so late when the async chain completes instead of doing so in probe ? I think it's fine doing this here or during probe (after registering the v4l2_dev the video devices. If you do it here and the remote subdev doesn't probe you won't have any media graph. If you do it in probe() and the remote subdev fails to probe, the media graph will register but be unusable. Not sure what's best, maybe an incomplete graph is easier to debug than no graph at all, but I won't push for this. Up to you :)
Will move it to probe()
+}I'm not against using notify_complete() but I suspect you have a single remote async subdev, right ? (iow you could have done this in _bound ? )
Yes, will do this in _bound.

I know it's equivalent since the union only stores pointers but it might be confusing... I don't know, some parts of me like it, some doesn't and would prefer something like union rkisp1_ext_params_config. Clever hack btw ;) If you prefer this style I'm fine with you keeping it even if seeing a parameter passed by value to the handlers makes me cringe a bit

I admit I have not tried to fully understand the scaler programming part at the beginning, but I trust you know the HW better than me :)
Will remove sink_streams.
The stats driver looks ok as well. I hope next version will be good to go, and I hope to be able to test this implementation soon using libcamera! Great work! Thanks j
Thanks very much! :)
