Hi,
The first patch in this series add support to async page flips, but it doesn't improve the refresh rate when using vidi+fimd.
The second patch fixes an issue on vidi that solves the refresh rate issue when only vidi is used. For the case where vidi + fimd is used it improves the refresh rate from 20Hz to 28Hz. There is room to improve this more, but I think these patches can already be pushed upstream.
It is important to remember that the low refresh rate issue only happens when vidi is used along with another crtc. It doesn't happen in a setup that has only FIMD and/or Mixer, thus most of use cases out there are not affected.
