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
