Hi,
this set of patches is based on work that I had done some 2-3 years ago to enable DP support on Pixel C. I never really got that to work, but I recently got my hands on newer hardware with DP connectivity, so I went to revive these patches.
I think this takes into account all review comments I was able to find and adds a bit of kerneldoc here and there. I've got a couple of patches on top of this that implement DP support (and make use of more of these helpers in the existing eDP support) for Tegra.
