Subject: [PATCH] drm/bridge: lt9611uxc: Increase EDID wait time from 500ms to 1000ms
Date: Fri, 21 Nov 2025 19:12:06 +0530 [thread overview]
Message-ID: <20251121-hdmibridge-v1-1-14c63890f362@oss.qualcomm.com> (raw)
EDID interrupt was coming 600-650 ms after HPD interrupt, resulting
into EDID read timeout and default resolution of 1024x768 on display.
