From 438cf3271ca116253cffb8edce8aba0191327682 Mon Sep 17 00:00:00 2001 From: Luca Ceresoli Date: Mon, 14 Aug 2023 15:40:24 +0200 Subject: [PATCH] drm/panel: simple: Fix Innolux G156HCE-L01 LVDS clock This panel has been implemented in commit eae7488814b5 ("drm/panel-simple: Add Innolux G156HCE-L01 panel entry") with a higher clock than the typical one mentioned on the documentation to avoid flickering on the unit tested. Testing on a different unit shows that the panel actually works with the intended 70.93 MHz clock and even lower frequencies so the flickering is likely caused either by a defective unit or by other different components such as the bridge.
