Nothing they can do about the specification. There is a DSI driver in the proprietary firmware, but there is also an open-source upstream version: https://github.com/anholt/linux/wiki/Raspberry-Pi-and-other-MIPI-DSI-display-panels https://github.com/anholt/linux/wiki/Raspberry-Pi-and-other-... This is a theme with the RPi. They generally implement new hardware in their proprietary firmware first, for lack of skills/time to do a proper upstream job of it (or the convience of copy-pasting some vendor code), then pay someone to develop an open-source driver. For example, here is a massive 80 patch series nearing merge for the new display pipeline in the RPi 4: https://patchwork.freedesktop.org/series/73839/ https://patchwork.freedesktop.org/series/73839/
