This DDIC is essential for panels used in OnePlus 6 and Pixel 3a XL (SDC variant). With proper support, all downstream patches in sdm845-mainline and sdm670-mainline can be dropped.
The mainline driver was broken so far, and with my recent introduction of S6E3FC2X01 driver, I had to "break it even more" due to OnePlus 6 common device-tree changes which defined all the regulators and corrected properties. At this moment the first version of the patchset will not include Pixel 3a XL (SDC) as no testers yet volunteered. The code, including the Pixel 3a XL enhancement can be found at https://gitlab.com/dhxx/linux/-/tree/b4/sofef00-rebuild Due to some unknown issues with -next-20251103 - 04, the code is based on few previous patchsets and v6.18-rc4 (or later).
