From 8d5d063fd669a0b059b035e74cff570a17953a77 Mon Sep 17 00:00:00 2001 From: Drew Davenport <ddavenport@chromium.org> Date: Thu, 17 Nov 2022 13:38:48 -0700 Subject: [PATCH] drm/panel-samsung-atna33xc20: Extend autosuspend delay Avoid the panel oscillating on and off during boot. In some cases it will be more than 1000ms between powering the panel to read the EDID early during boot, and enabling the panel for display. Extending the autosuspend delay avoids autosuspending during this interval.
