Merge tag 'topic/mst-suspend-resume-reprobe-2019-10-29-2' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
UAPI Changes:
Cross-subsystem Changes:
Core Changes:
* Handle UP requests asynchronously in the DP MST helpers, fixing
hotplug notifications and allowing us to implement suspend/resume
reprobing
* Add basic suspend/resume reprobing to the DP MST helpers
* Improve locking for link address reprobing and connection status
request handling in the DP MST helpers
* Miscellaneous refactoring in the DP MST helpers
* Add a Kconfig option to the DP MST helpers to enable tracking of
gets/puts for topology references for debugging purposes
Driver Changes:
* nouveau: Resume hotplug interrupts earlier, so that sideband
messages may be transmitted during resume and thus allow
suspend/resume reprobing for DP MST to work
* nouveau: Avoid grabbing runtime PM references when handling short DP
pulses, so that handling sideband messages in resume codepaths with the
DP MST helpers doesn't deadlock us
* i915, nouveau, amdgpu, radeon: Use detect_ctx for probing MST
connectors, so that we can grab the topology manager's atomic lock
Note: there's some amdgpu patches that I didn't realize were pushed
upstream already when creating this topic branch. When they fail to
apply, you can just ignore and skip them.
