Devarsh, the three fixes from my July testing on the PIXPAPER 4.26m are still available: https://lore.kernel.org/all/20260731-ssd16xx-pixpaper-rpi5-v1-0-18ffc0dbf59a@gmail.com/ I am happy to rebase them, reshape them into whatever form fits your series best, or retest on a newer kernel - whatever is most convenient for you. There is no hurry at all from my side; please just let me know if anything would be useful, and thank you again for making room for the panel in your work. Thomas, may I ask your advice on how best to handle the panel support in the meantime? The PIXPAPER 4.26m is the only SSD16xx hardware I have, so everything I can contribute is limited to this one panel, and its support has been on hold since June waiting for the shared driver. I wondered whether it might be acceptable to merge the standalone PIXPAPER driver as an interim step, on the understanding that I convert the panel over to ssd16xx and remove the standalone driver once the shared driver lands. I realise that is not ideal, and I may well be missing a better option - if you would prefer to wait for the shared driver, I am perfectly happy to do that instead. I would rather follow your judgement than guess. Thank you both for the review time so far. Regards, LiangCheng
