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.
Best regards,
Tomasz

Hi,
This is about a TV stick called MK808.
Enabled VOP an HDMI for rk3066.
Able to see pinguins at boot.
Found similar bug reports for rk3399.

This patch doesn't seem to work for me.

Compared to rk3399 the rk3066 doesn't seem to have iommu.
