Hi Johan, It looks like VOP on RK3066 is not officially supported by upstream, so what you're seeing is not a bug, it's just expected behavior, because nobody had the time (or need) to enable support for your hardware yet.
I added all the people that may be potentially thinking to add support for this SoC, but they have no obligation to do so. If you are in an urgent need, I think you may have more luck asking your hardware or SoC vendor directly.
