From 99ed392209ccce08b2bc2887b433269a28b85496 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 8 Sep 2022 16:54:53 +0800 Subject: [PATCH] drm/panel-edp: Fix delays for Innolux N116BCA-EA1 [ Upstream commit 8f7115c1923cd11146525f1615beb29018001964 ] Commit 52824ca4502d ("drm/panel-edp: Better describe eDP panel delays") clarified the various delays used for eDP panels, tying them to the eDP panel timing diagram. For Innolux N116BCA-EA1, .prepare_to_enable would be: t4_min + t5_min + t6_min + max(t7_max, t8_min) Since t4_min and t5_min are both 0, the panel can use either .enable or .prepare_to_enable. As .enable is better defined, switch to using .enable for this panel. Also add .disable = 50, based on the datasheet's t9_min value. This effectively makes the delays the same as delay_200_500_e80_d50.
