This can help drivers to make somewhat intelligent decisions in their ->detect callback: If the connector is hpd capable and in the unknown state, the driver needs to force a full detect cycle. Otherwise it could just (if it chooses so) to update the connector state from it's hpd handler directly, and always return that in the ->detect callback. Atm only drm/i915 calls drm_mode_config_reset at resume time, so other drivers would need to add that call first before using this facility.
