The DP MST bindings were A-b'ed and R-b'ed by Rob, so I picked them up
into msm-next-lumag. Please rebase your patchset on top of it and
resend. At this point I'm interested in DP bindings and DP driver
patches, the PHY part can come up separately.

As for the compatibilities, I think DP on SM6150 should be compatible
with either DP on SDM845 or DP on SM8350. Please choose one which suits
better.
