I'm not sure you can. My understanding of moderm ARM SOCs is this.
The kernel maintains separate pipelines for graphics and video. It is
only in the ARM SOC hardware, directly before sending output to the
display, that the two pipelines are merged.
Note that the video pipeline is often
image there are more than one display buffer(let's say two frame buffer),
the hardware will merge two buffer and send to the screen
in most modern arm cpu, such kind of hardware is always exist
