At a high level I don't have any major issues with the set. There are some rough edges that I noticed as I was reading it (as would any patch of this size), but I think it's probably not a good use of either of our time for me to nitpick 10k lines of code over multiple iterations. So in the interest of not letting the perfect get in the way of the good, I suggest we apply the set and fix up as time and necessity allow.

These patches add support for Display-Port driver on SnapDragon 845 hardware. It adds DP driver and DP PLL driver files along with the needed device-tree bindings.
