My sensor can work at any fps (even fractional) up to 60 fps with its default frame size or even higher when using crop or "binning'. That fact is reflected in my previous implemetation of VIDIOC_ENUM_FRAMEINTERVALS, which answered with a V4L2_FRMIVAL_TYPE_CONTINUOUS-type reply. This seem not possible anymore because of the lack of the needed fields in the 'struct v4l2_subdev_frame_interval_enum' used to delegate the question to the subdev driver. V4L2_FRMIVAL_TYPE_STEPWISE does not seem possible anymore either. Has that been replaced by something else or is that functionality not considered relevant anymorea ?
