Thanks Rob for pushing the changes. I confirm that the versions which you have pushed are the latest ones.

I have rebased audio changes on top of the latest DP changes
and posted them here https://patchwork.freedesktop.org/series/81612/.
The other DP change which is missing is the video pattern CTS change https://patchwork.freedesktop.org/series/81614/ which
also I have now rebased on top of the latest DP patch series and posted.

Thanks

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.

BR,

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.

The block diagram of DP driver is shown below:
