Subject: [PATCH] drm/panel: simple: Fix Innolux G156HCE-L01 LVDS clock
Date: Fri, 4 Aug 2023 17:10:10 +0200 [thread overview]
Message-ID: <20230804151010.834990-1-luca.ceresoli@bootlin.com> (raw)
This panel has been implemented in commit 225213f24c79 ("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.
Fixes: 225213f24c79 ("drm/panel-simple: Add Innolux G156HCE-L01 panel entry")
