Adding support for those two ioctls are trivial, and allow testing different resolutions with the driver.
Together with some improvements I made at camorama, it is now possible to change the atomisp sensor's resolution at the GUI.
Talking about camorama, I also added there an option to disable the Gtk cairo_scale() calls. On my tests here, placing ov2680 on its maximum resolution, I'm getting a framerate of 26 fps, which sounds reasonable, as the maximum would be 30fps, and I'm not using daylight.
When letting cairo_scale() to run, the rate reduces to 8 fps, meaning that Gtk is not using GPU acceleration.
Funny enough, when resolution is lower, atomisp is giving a very bad framerate (around 3fps, even with the scaler disabled).
This is a very weird result, probably indicating some problems inside the driver. That requires further investigation.
