It's the .timeperframe member of struct v4l2_captureparm, that you'd be looking at. And yes, you'd have to add support for it to soc-camera, by adding a suitable operation to struct soc_camera_host_ops, and calling it from soc_camera.c - if provided by the host driver. Then you add it to sh_mobile_ceu_camera.c and just call .s_parm from struct v4l2_subdev_video_ops. I'm replying to this email with two patches, please, see if they provide the necessary infrastructure for you and let me know the result - I'll push them upstream if you're fine with them.
