[PATCH 00/12] drm/i915: Fix HPD handling during driver init/shutdown

[Imre Deak <imre.deak@intel.com>]

Fix the handling of display connector hotplug handling during the driver
init/shutdown sequences. A hotplug event can result in a connector
detection/modeset running in parallel with the HW programming of the
init/shutdown sequence, or when the display IRQs are disabled already.

Also fix incorrectly detecting a disconnected state due to glitches on
the HPD line and prevent long timeout/retry delays during DP AUX
transfers on all DP connectors.

Imre Deak (12):
  drm/i915: Init DRM connector polled field early
  drm/i915: Keep the connector polled state disabled after storm
  drm/i915: Move audio deinit after disabling polling
  drm/i915: Disable intel HPD poll after DRM poll init/enable
  drm/i915: Suspend the framebuffer console during driver shutdown
  drm/i915: Suspend the framebuffer console earlier during system
    suspend
  drm/i915: Prevent modesets during driver init/shutdown
  drm/i915: Disable hotplug detection works during driver init/shutdown
  drm/i915: Disable hotplug detection handlers during driver
    init/shutdown
  drm/i915: Add intel_digital_port lock/unlock hooks
  drm/i915: Filter out glitches on HPD lines during hotplug detection
  drm/i915/dp: Abort AUX on disconnected native DP ports
