Merge tag 'drm-msm-next-2019-06-25' of https://gitlab.freedesktop.org/drm/msm into drm-next

+ usual progress on cleanups
+ dsi vs EPROBE_DEFER fixes
+ msm8998 (snapdragon 835 support)
  + a540 gpu support (mesa support already landed)
  + dsi, dsi-phy support
+ mdp5 and dpu interconnect (bus/memory scaling) support
+ initial prep work for per-context pagetables (at least the parts that
  don't have external dependencies like iommu/arm-smmu)

There is one more patch for fixing DSI cmd mode panels (part of a set of
patches to get things working on nexus5), but it would be conflicty with
1cff7440a86e04a613665803b42034 in drm-next without rebasing or back-merge,
and since it doesn't conflict with anything in msm-next, I think it best
if Sean merges that through drm-mix-fixes instead.

(In other news, I've been making some progress w/ getting efifb working
properly on sdm850 laptop without horrible hacks, and drm/msm + clk stuff
not totally falling over when bootloader enables display and things are
already running when driver probes.. but not quite ready yet, hopefully
we can post some of that for 5.4.. should help for both the sdm835 and
sdm850 laptops.)
