Hi all, We are developing a v4l2 subdevice driver to be able to support the imx378 sensor and upstream it. But we would like to have a continuous frame interval and the current VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL ioctl implementation doesn't support it. How can we proceed here? Can we maybe add the limits by using the reserved area of v4l2_subdev_frame_interval_enum struct? Something similar to v4l2_subdev_frame_size_enum is doing with continuous frame size. I guess it would also need to adapt v4l2-ctl, v4l2-compliance and so on but not really sure about the whole impact in linuxtv/linux-media of this need. Thanks in advance, Daniel
