Subject: [PATCH] drm/panel-edp: Add panel used by T14s Gen6 Snapdragon (OLED)
Date: Thu, 20 Mar 2025 12:47:09 +0000 [thread overview]
Message-ID: <20250320-wip-obbardc-qcom-t14s-oled-panel-v1-1-05bc4bdcd82a@linaro.org> (raw)
The Lenovo Thinkpad T14s Gen6 Snapdragon OLED model has a Samsung
panel. The kernel currently prints a warning due to not having the
correct timings.
This panel appears to work with the default conservative timings,
so add the OLED panel to the list of supported panels with default
timings.
The raw EDID is:
