@erebion alright i'll bite, come find me at congress and i'll see what i can do! i think your time estimate might be a little optimistic though xD
rather than just answer your questions i would rather teach you how to find the answers (e.g reading driver code and devicetree bindings) assuming that's stuff you're interested in learning?
with what little is explained in your thread and on that repo i would estimate more like 1-3 weeks of work for me to fix touch, bluetooth, and maybe start looking into camera/audio
knowing who to ask and what to ask is a big part of the learning curve tbh
