[PATCH v3 0/3] handle HPD polling on display pm runtime s/r

[Vinod Govindapillai]

Switch to HPD polling on display pm runtime suspend to enable
HPDs on runtime suspend scenario.

While xe_display_pm_suspend/resume() performs steps during runtime
suspend/resume that shouldn't happen, like suspending MST and they are
missing other steps like enabling DC9, this patchset is meant to keep
the current behavior wrt. these, leaving the corresponding updates for
a follow-up

Imre Deak (2):
  drm/xe: Suspend/resume user access only during system s/r
  drm/xe: Handle polling only for system s/r in
    xe_display_pm_suspend/resume()

Vinod Govindapillai (1):
  drm/xe/display: handle HPD polling in display runtime suspend/resume
