There's no single place. Ideally this question should be answered by "use the mainline kernel", and eventually it will. I'm aware of three maintained kernel trees specifically for PinePhone: Samuel's: https://github.com/smaeul/linux https://github.com/smaeul/linux Mine: https://github.com/megous/linux/ https://github.com/megous/linux/ Pine64: https://gitlab.com/pine64-org/linux/commits/pine64-kernel-5.7.y https://gitlab.com/pine64-org/linux/commits/pine64-kernel-5.... I think at the moment all of those are pretty much equivalent feature-wise, except for some mild differences. It's not possible to workaround (in software) anything that requires CC pins to work properly, that includes setting up display port alternate mode.
