Thanks for your sample code, and your implementation is different than Matthias' version. In your version, mmsys is a single device which has clock function and display function, the clock function is placed in clock driver folder and display function is placed in drm driver folder. In Matthias' version, clock function is a sub device of mmsys. I've no idea of which one is better. I would get more information to make better decision.
