Subject: [PATCH] drm/panel: kingdisplay-kd097d04: Disable EoTp
Date: Tue, 28 Oct 2025 22:38:12 +0100 [thread overview]
Message-ID: <20251028214045.1944956-1-dev@dwurp.de> (raw)
Since commit d97e71e44937 ("drm/bridge: synopsys: dw-mipi-dsi: enable EoTp by
default") panel output on an Acer Chromebook Tab 10 (google-dru) is corrupted.
The tablet I use is equipped with a kingdisplay-kd097d04 panel, disabling EoTp
restores the correct functionality.
Fixes: d97e71e44937 ("drm/bridge: synopsys: dw-mipi-dsi: enable EoTp by default")
Signed-off-by: Sebastian Fleer <dev@dwurp.de>
