Yeah, I'd agree with Dmitry here. To the last person who wanted to add a Samsung OLED panel, I replied [1] It's much more likely that this should use the `panel-samsung-atna33xc20.c` driver, which gets the timings more correct for Samsung OLED panels (there's an extra GPIO it needs to manage). To use that driver, you'll actually just need to need to add a new compatible and use the existing one as a fallback. See recent changes to: Documentation/devicetree/bindings/display/panel/samsung,atna33xc20.yaml [1] https://lore.kernel.org/r/CAD=FV=X+WnSKZTFhzdXEFfpKCEqfPDc77h7oG=ZU6Nqq6XHOmA@xxxxxxxxxxxxxx
