Subject: [PATCH v1] drm/edp-panel: Add panel used by T14s Gen6 Snapdragon
Date: Tue, 11 Feb 2025 02:41:01 +0100 [thread overview]
Message-ID: <20250211014314.94429-1-sre@ring0.de> (raw)
From: Sebastian Reichel <sre@kernel.org>
The Lenovo Thinkpad T14s Gen6 Snapdragon is currently sold with three
different panel versions: OLED, Low Power IPS or IPS with Touchscreen.
My Low Power IPS version had this panel and the kernel complained
about not knowing any details. I don't have any panel documentation,
but as far as I can see the same timings for the already supported
CSO panel also work for this one.
The raw EDID is:

Hi,
I'm running my kernels on the laptop as a daily driver with this patch
for ca. 3 weeks now and haven't noticed any problems. In case they have
better documentation I added some people in Cc, that have send patches
for the T14s DT and thus should have at least one of them.
Greetings,
-- Sebastian
