Hi Hans & Sakari A question raised from review of [1]: Is it correct that any subdevice driver that supports any controls should advertise V4L2_SUBDEV_FL_HAS_EVENTS and have subscribe_event/unsubscribe_event core_ops? I added that patch for ov9282 to resolve a v4l2-compliance failure: fail: v4l2-test-controls.cpp(835): subscribe event for control 'User Controls' failed test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: FAIL but it surprised Jacopo, and he has observed that many of the current drivers with controls don't meet this requirement. I just wanted confirmation from those in the know. Thanks Dave [1] https://patchwork.linuxtv.org/project/linux-media/patch/20221005152809.3785786-17-dave.stevenson@xxxxxxxxxxxxxxx/
