" IT8951 Update (2019-11-03)
Support for IT8951 based displays kindly provided by @fimad has been merged. This means that Waveshare 6", 7.8", 9.7" and 10.3" may work since they use this controller. At least the 6" and 9.7" displays have been verified to work. A big thanks to everyone involved with the discussion and code contributions (https://github.com/joukos/PaperTTY/issues/25)!"
Pretty interesting, would be interested to see this with the Rpi400 or in a PiTop
