Fyi, I've pushed this series and the dp-compliance bits to
msm-next-dp[1]
I didn't include the dp audio series yet, which seems to need some
minor rebasing. (And a small request, when resending, cc
freedreno@xxxxxxxxxxxxxxxxxxxxx, so it shows up in the patchwork
instance[2] I use)
You might want to double check that I got the correct versions of the
series, etc. And that nothing else (other than audio) is missing.
Thanks Rob for pulling changes in msm-next-dp branch.
I confirm that changes you pointed above are latest
changes and nothing else is missing in driver.
Sure, we will make sure to send changes in freedreno list as well.
Thanks.

These patches add Display-Port driver on SnapDragon/msm hardware.
This series also contains device-tree bindings for msm DP driver.
It also contains Makefile and Kconfig changes to compile msm DP
driver.
