Merge tag 'drm-msm-next-2018-07-30' of git://people.freedesktop.org/~robclark/linux into drm-next
A bit larger this time around, due to introduction of "dpu1" support
for the display controller in sdm845 and beyond. This has been on
list and undergoing refactoring since Feb (going from ~110kloc to
~30kloc), and all my review complaints have been addressed, so I'd be
happy to see this upstream so further feature work can procede on top
of upstream.
Also includes the gpu coredump support, which should be useful for
debugging gpu crashes. And various other misc fixes and such.
