Subject: [PATCH] drm/panel/panel-edp: Add CSOT MPP36 T9 eDP panel
Date: Wed, 29 Apr 2026 16:52:51 +0200 [thread overview]
Message-ID: <20260429145251.8445-1-adamszyma@wp.pl> (raw)
Add support for the CSOT MPP36 T9 eDP panel (manufacturer ID: CSW,
product ID: 0x143d) used in the Dell Inspiron 14 Plus 5441 laptop.
Without this entry the kernel logs:
panel-simple-dp-aux: Unknown panel CSW 0x143d, using conservative timings
and brightness control is non-functional on affected devices.
