[PATCH v3 0/4] Add DRM driver for LG LH609QH1 Panel with SiliconWorks SW49410 DDIC
From: Paul Sajna
Date: Sun Jun 14 2026 - 20:08:34 EST
This patch series adds a drm panel driver for the LG SW49410 panel found
in the LG G7 ThinQ (codename judyln).
The basic driver skeleton was generated by https://github.com/msm8916-mainline/linux-mdss-dsi-panel-driver-generator
from the vendor device-tree.
There seems to still be some power supply issues, the bottom-left corner
of the screen is dark, and the rest of the screen develops shadow-y
burn-in-like patterns when resumed after being left off for a while.
