[Intel-gfx] [v3] drm/i915: Add detection of changing of edid on between suspend and resume

2018-08-09 Thread Gwan-gyeong Mun
The hotplug detection routine of i915 uses drm_helper_hpd_irq_event(). This helper can detect changing of status of connector, but it can not detect changing of edid. Following scenario requires detection of changing of edid. 1) plug display device to a connector 2) system suspend 3) unplug
