Just to make it clear. Like I already pointed [1], this version breaks Exynos boards with DSI panels. Either the patch #1 has to be dropped to keep the current hack (the current code changes the bridge order to force proper pre_enable calls) or the Dave's patches have to be applied first [3].

Yes, I understand overall. Working on checking Dave's changes in the Allwinner DSI host. If it doesn't impact it I will send next version by including Dave's patches. Thanks, Jagan.
