Re: [PATCH v12 0/5] Add support for DisplayPort driver on SnapDragon

From: Rob Clark

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,
